This book was released on 2013 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet the demands for continuous transistor scaling and performance improvements required by the ITRS, there has been a tremendous amount of effort related to alternative high mobility channel materials as potential Si replacements for MOSFET fabrication. Two particularly attractive material systems include III-V substrates and graphene. Thus far, the high trap density which characterizes high-k dielectrics and the III-V/high-k dielectric interface remains an obstacle to III-V substrate integration. In a first aspect of this work, charge traps within the gate stack of III-V MOSFETs, as well as at the III-V/dielectric interface, were examined to better understand their impact on III-V device performance. In particular, a pulsed I-V measurement technique was used to assess the impact of fast and slow transient charging effects on various III-V transistors with ALD-deposited Al2O3 gate dielectric. The charge pumping technique was also utilized to determine the density of interface traps, including their energy distribution and position profile, providing further understanding into the nature of traps in the III-V/high-k system. Graphene has also attracted considerable interest owing to its high intrinsic mobility, large current densities, thermodynamic and mechanical stability. Yet, a primary challenge to the integration of graphene substrates is the lack of high quality, large-area graphene. Thus, in another aspect of this work, large-area graphene was synthesized by CVD of acetylene on Co thin films, and the influence of Co film thickness on graphene synthesis was studied. Resulting graphene films were characterized using Raman spectroscopy and back-gated GFETs were fabricated. Taking advantage of graphene’s intrinsic ambipolar electron-hole symmetry, GFET frequency doublers were fabricated on low-capacitance, single-crystal quartz substrates. GFETs frequency doublers were found to operate beyond their transit frequency (fT), and in the limit of vanishing device non-idealities, their maximum conversion gain was determined to approach a near lossless value. To further understand and improve GFET RF performance, the impact of parasitic resistances was experimentally examined. RF measurements as a function of temperature and modulated access resistance highlight the strong influence of RC on scaled devices, while the impact of RA becomes more evident for devices with large access regions.

Download or read book High Mobility and Quantum Well Transistors written by Geert Hellings and published by Springer Science & Business Media. This book was released on 2013-03-25 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many decades, the semiconductor industry has miniaturized transistors, delivering increased computing power to consumers at decreased cost. However, mere transistor downsizing does no longer provide the same improvements. One interesting option to further improve transistor characteristics is to use high mobility materials such as germanium and III-V materials. However, transistors have to be redesigned in order to fully benefit from these alternative materials. High Mobility and Quantum Well Transistors: Design and TCAD Simulation investigates planar bulk Germanium pFET technology in chapters 2-4, focusing on both the fabrication of such a technology and on the process and electrical TCAD simulation. Furthermore, this book shows that Quantum Well based transistors can leverage the benefits of these alternative materials, since they confine the charge carriers to the high-mobility material using a heterostructure. The design and fabrication of one particular transistor structure - the SiGe Implant-Free Quantum Well pFET – is discussed. Electrical testing shows remarkable short-channel performance and prototypes are found to be competitive with a state-of-the-art planar strained-silicon technology. High mobility channels, providing high drive current, and heterostructure confinement, providing good short-channel control, make a promising combination for future technology nodes.

This book was released on 2017-02-28 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helps readers understand the physics behind MOS devices for low-voltage and low-energy applications Based on timely published and unpublished work written by expert authors Discusses various promising MOS devices applicable to low-energy environmental and biomedical uses Describes the physical effects (quantum, tunneling) of MOS devices Demonstrates the performance of devices, helping readers to choose right devices applicable to an industrial or consumer environment Addresses some Ge-based devices and other compound-material-based devices for high-frequency applications and future development of high performance devices. "Seemingly innocuous everyday devices such as smartphones, tablets and services such as on-line gaming or internet keyword searches consume vast amounts of energy. Even when in standby mode, all these devices consume energy. The upcoming 'Internet of Things' (IoT) is expected to deploy 60 billion electronic devices spread out in our homes, cars and cities. Britain is already consuming up to 16 per cent of all its power through internet use and this rate is doubling every four years. According to The UK's Daily Mail May (2015), if usage rates continue, all of Britain's power supply could be consumed by internet use in just 20 years. In 2013, U.S. data centers consumed an estimated 91 billion kilowatt-hours of electricity, corresponding to the power generated by seventeen 1000-megawatt nuclear power plants. Data center electricity consumption is projected to increase to roughly 140 billion kilowatt-hours annually by 2020, the equivalent annual output of 50 nuclear power plants." —Natural Resources Defense Council, USA, Feb. 2015 All these examples stress the urgent need for developing electronic devices that consume as little energy as possible. The book “MOS Devices for Low-Voltage and Low-Energy Applications” explores the different transistor options that can be utilized to achieve that goal. It describes in detail the physics and performance of transistors that can be operated at low voltage and consume little power, such as subthreshold operation in bulk transistors, fully depleted SOI devices, tunnel FETs, multigate and gate-all-around MOSFETs. Examples of low-energy circuits making use of these devices are given as well. "The book MOS Devices for Low-Voltage and Low-Energy Applications is a good reference for graduate students, researchers, semiconductor and electrical engineers who will design the electronic systems of tomorrow." —Dr. Jean-Pierre Colinge, Taiwan Semiconductor Manufacturing Company (TSMC) "The authors present a creative way to show how different MOS devices can be used for low-voltage and low-power applications. They start with Bulk MOSFET, following with SOI MOSFET, FinFET, gate-all-around MOSFET, Tunnel-FET and others. It is presented the physics behind the devices, models, simulations, experimental results and applications. This book is interesting for researchers, graduate and undergraduate students. The low-energy field is an important topic for integrated circuits in the future and none can stay out of this." —Prof. Joao A. Martino, University of Sao Paulo, Brazil

Download or read book Analytical Modelling of Breakdown Effect in Graphene Nanoribbon Field Effect Transistor written by Iraj Sadegh Amiri and published by Springer. This book was released on 2017-10-29 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses analytical approaches and modeling of the breakdown voltage (BV) effects on graphene-based transistors. It presents semi-analytical models for lateral electric field, length of velocity saturation region (LVSR), ionization coefficient (α), and breakdown voltage (BV) of single and double-gate graphene nanoribbon field effect transistors (GNRFETs). The application of Gauss’s law at drain and source regions is employed in order to derive surface potential and lateral electric field equations. LVSR is then calculated as a solution of surface potential at saturation condition. The ionization coefficient is modelled and calculated by deriving equations for probability of collisions in ballistic and drift modes based on the lucky drift theory of ionization. The threshold energy of ionization is computed using simulation and an empirical equation is derived semi-analytically. Lastly avalanche breakdown condition is employed to calculate the lateral BV. On the basis of this, simple analytical and semi-analytical models are proposed for the LVSR and BV, which could be used in the design and optimization of semiconductor devices and sensors. The proposed equations are used to examine BV at different channel lengths, supply voltages, oxide thickness, GNR widths, and gate voltages. Simulation results show that the operating voltage of FETs could be as low as 0.25 V in order to prevent breakdown. However, after optimization, it can go as high as 1.5 V. This work is useful for researchers working in the area of graphene nanoribbon-based transistors.
