Book excerpt: Emerging wide bandgap (WBG) semiconductors hold the potential to advance the global industry in the same way that, more than 50 years ago, the invention of the silicon (Si) chip enabled the modern computer era. SiC- and GaN-based devices are starting to become more commercially available. Smaller, faster, and more efficient than their counterpart Si-based components, these WBG devices also offer greater expected reliability in tougher operating conditions. Furthermore, in this frame, a new class of microelectronic-grade semiconducting materials that have an even larger bandgap than the previously established wide bandgap semiconductors, such as GaN and SiC, have been created, and are thus referred to as “ultra-wide bandgap” materials. These materials, which include AlGaN, AlN, diamond, Ga2O3, and BN, offer theoretically superior properties, including a higher critical breakdown field, higher temperature operation, and potentially higher radiation tolerance. These attributes, in turn, make it possible to use revolutionary new devices for extreme environments, such as high-efficiency power transistors, because of the improved Baliga figure of merit, ultra-high voltage pulsed power switches, high-efficiency UV-LEDs, and electronics. This Special Issue aims to collect high quality research papers, short communications, and review articles that focus on wide bandgap device design, fabrication, and advanced characterization. The Special Issue will also publish selected papers from the 43rd Workshop on Compound Semiconductor Devices and Integrated Circuits, held in France (WOCSDICE 2019), which brings together scientists and engineers working in the area of III–V, and other compound semiconductor devices and integrated circuits.

Available in PDF, EPUB and Kindle. Book excerpt: Compared to traditional silicon (Si) semiconductor material, wide bandgap (WBG) materials like silicon carbide (SiC) and gallium nitride are gradually applied to fabricate power semiconductor devices, which are used in power converters to achieve high power efficiency, high operation temperature and high switching frequency. As those power devices are relatively new, their characterization and modeling are important to better understand their characteristics for better use. This dissertation is mainly focused on those WBG power semiconductor devices characterization, modeling and fast switching currents measurement. In order to measure their static characteristics, a single-pulse method is presented. A SiC diode and a "normally-off" SiC JFET is characterized by this method from ambient temperature to their maximal junction temperature with the maximal power dissipation around kilowatt. Afterwards, in order to determine power device inter-electrode capacitances, a measurement method based on the use of multiple current probes is proposed and validated by measuring inter-electrode capacitances of power devices of different technologies. Behavioral models of a Si diode and the SiC JFET are built by using the results of the above characterization methods, by which the evolution of the inter-electrode capacitances for different operating conditions are included in the models. Power diode models are validated with the measurements, in which the current is measured by a proposed current surface probe.

Available in PDF, EPUB and Kindle. Book excerpt: Wide bandgap semiconductors are receiving extensive attention due to their exceptional physical and chemical properties making them useful for high efficiency and high power electronic devices. Comparing other conventional wide bandgap materials, monoclinic Îø-Ga2O3 also represents an outstanding semiconductor oxide for next generation of UV optoelectronics and high temperature sensors due to its wide band gap (~4.9eV). This new semiconductor material has higher breakdown voltage (8MV/cm) and n-type conductivity which make it more suitable for potential application as high power electronics. The properties and potential applications of these wide bandgap materials have not yet fully explored. In this study, the growth and characterization of single crystal b-Ga2O3 thin films grown on c-plane sapphire (Al2O3) substrate using two different techniques; molecular beam epitaxy (MBE) and pulsed laser deposition (PLD) techniques has been investigated. The influence of the growth parameters of MBE and PLD on crystalline quality and surface has been explored. Two methods have been used to grow Ga2O3 using MBE; one method is to use elemental Ga and the second is the use of a polycrystalline Ga2O3 compound source with and without an oxygen source. Using the elemental Ga source, growth rate of b-Ga2O3 thin films was limited due to the formation and desorption of Ga2O molecules. In order to mitigate this problem, a compound Ga2O3 source has been introduced and used for the growth of crystalline b-Ga2O3 thin films without the need for additional oxygen since this source produces Ga-O molecules and additional oxygen. Two different alloys (InGa)2O3 and (AlGa)2O3 has been grown on c-plane sapphire substrate by pulsed laser deposition technique to tune the bandgap of the oxide thin films from 3.5-8.6 eV suitable for applications such as wavelength-tunable optical devices, solid-state lighting and high electron mobility transistors (HEMTs). The crystallinity, chemical bonding, surface morphology and optical properties have been systematically evaluated by a number of in-situ and ex-situ techniques. The crystalline Ga2O3 films showed pure phase of (2 Ì501) plane orientation and in-plane XRD phi-scan exhibited the six-fold rotational symmetry for b-Ga2O3 when grown on sapphire substrate. The alloys exhibit different phases has been stabilized depending on the compositions. Finally, a metal-semiconductor-metal (MSM) structure deep-ultraviolet (DUV) photodetector has been fabricated on Îø-Ga2O3 film grown with an optimized growth condition has been demonstrated. This photodetector exhibited high resistance as well as small dark current with expected photoresponse for 254 nm UV light irradiation suggesting Îø-Ga2O3 thin films as a potential candidate for deep-UV photodetectors. While the grown Ga2O3 shows high resistivity, the electrical properties of (In0.6Ga0.4)2O3 and (In0.8Ga0.2)2O3 alloys show low resistivity with a high carrier concentration and increasing mobility with In content.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation investigates the propagation of information between models of disparate computational complexity and simulation domains with specific focus on the modeling of wide bandgap semiconductors for power electronics applications. First, analytical physics models and technology computer-aided design numerical physics models are presented. These types of physics models are contrasted by ease of generation and computational complexity. Next, processes generating transient simulations from these models are identified. Mixed-mode simulation and behavioral device models are established as two available options. Of these two, behavioral models are identified as the method producing superior computational performance due to their much-reduced simulation time. A comparison of switching performance for two wide bandgap field-effect transistors manufactured with the same process is next presented. Empirical and simulated switching results demonstrate that available models predict the slew rates reasonably well, but fail to accurately capture ringing frequencies. This is attributed to two primary causes; the modeling tool used for this comparison is incapable of producing a sufficiently high-quality fit to ensure accurate prediction and the devices are sensitive to parasitic values beyond the measurement uncertainty of the characterization hardware. To remedy this, a two-fold approach is necessary. First, a new model must be generated which is more capable of predicting steady-state performance. Second, a characterization procedure must be produced which tunes parameters beyond what is possible with empirical characterization. To the first point, a novel model based on the Curtice model is presented. The novel model adapts the Curtice model by adding gate-bias dependence to model parameters and introducing an exponential smoothing function to account for the gradual transition from linear to saturation exhibited by some wide bandgap field-effect transistors. Care is taken to model forward conduction, reverse conduction, and transfer characteristics with high accuracy. Non-linear capacitances are then modeled using a charge-based lookup table demonstrated by previous work in the literature to be effective. Thermal performance is accounted for with both the incorporation of thermal scaling factors and a thermal RC network to account for joule-heating. The proposed model is capable of capturing device steady-state and small-signal performance more precisely than previous models. A tuning and optimization procedure is next presented which is capable of tuning device model parasitic values within uncertainty bounds of characterization data. This method identifies the need for and introduces new model parameters intended to account for dispersive phenomena to a first degree. Pairing this method with the aforementioned model, significant improvements in transient agreement can be achieved for fast-switching devices. A method is also presented which identifies and quantifies the impact of parameters on transient performance. This process can be used to remove model parameters from the tuning set and possibly decouple parameter tuning. The propagation of these fully-tuned device and circuit models to the system level is next discussed. The cases of a buck converter and double pulse test are used as examples of dc switching circuits which may be used for switching characterization and to account for switching losses. Simulation is used to demonstrate that these circuits, when using similar components, produce comparable results. This allows the use of double pulse tests for switching characterization in simulation, thus eliminating the need for quasi-steady-state conditions to be reached in converter simulation. Methods are proposed for the inclusion of this data into system-level models such that simulation time will be minimally impacted. When used in conjunction, the methods presented in this chapter are sufficient to propagate information from the physics level all the way through to the system level. If specific circuits and system components are known, the impact of including a theoretical device can be assessed. This lends itself to advanced design of each type of model by analyzing the interactions predicted by various levels of models. This has serious implications for accelerating the deployment of wide bandgap semiconductor in power electronics by addressing the primary concerns of reliability and ease of implementation. By using these methods, devices, circuits, and systems can each be optimized to fully benefit from the theoretical advantages presented by wide bandgap semiconductor materials.
