This book was released on 2015 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different semiconducting types are applied in various fields of the semiconductor industry: organic, inorganic and hybrid. Each of these semiconducting types of materials have their own strengths as well as their weakness. Inorganic materials possess low absorption and high carrier mobility while organic materials possess high absorption and low carrier mobility. Inorganic/organic hybrid semiconducting devices take advantage of the mixing of these two types of semiconductors. By building a heterojunction with inorganic and organic materials, the advantages of each individual material is passes onto this new hybrid while cancelling out the disadvantages. In this master thesis, the fabrication procedure and characterization techniques are studied for inorganic, organic and hybrid semiconducting devices. For the inorganic materials, fabrication was performed in the MicroFabrication Facility in order to properly achieve small features in the micrometer range. Device processing was performed to achieve a high-electron mobility transistor using AlGaN/GaN and AlInN/GaN heterostructures. The fabrication procedure involved the defining of features through photolithography, ion mill etching, and electron-beam evaporation. Electrical characterization was performed on both heterostructures to make a comparison. The organic device studied was a photoconductor using the conducting polymer P3HT and an optical and electro-optic comparison was made with the addition of MWCNT into the polymer matrix. A hybrid pn-junction diode was fabricated using P3HT and electrical measurements were performed and analyzed through an equivalent circuit to characterize and compare it to a P3HT:MWCNT active layer for the pn-junction.

This book was released on 2008 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed and studied selected properties of a novel type of inorganic-organic hybrid semiconductor materials in order to enhance the functionality over their parent structures. Since inorganic organic hybrid semiconductor materials are composed of both inorganic and organic segments, one may expect them to have the advantage of combining the excellent electrical, optical, thermal and transport properties from the inorganic component with the flexibility, processability and structural diversity from the organic component. As a continuing effort, we have synthesized, modified, and characterized a number of selected structures with potential for solid state lighting applications. For example, we have developed the first inorganic organic semiconductor bulk material, double layered 2D-Cd2Q2(ba)(Q=S, Se), capable of producing direct white light. This type of materials could be promising for use as a single-material white-light-emitting source in white LEDs. Luminescence properties of these hybrid semiconductors can be tuned systematically by changing their composition and doping level. In addition, a thin pellet of one of our hybrid semiconductor materials without any modifications showed low electrical conductivity. Significant improvement may be anticipated with modifications. Solution processed deposition techniques provide great opportunities for optical and optoelectronic devices, such as displays, solid state lighting, and solar cells, because it enables to fabricate flexible devices with low-cost and large area fabrications. Most semiconductors show very low solubility in organic solvents, thus limiting the opportunities to prepare thin films using soluble precursors. In this study, we have developed a simple, efficient, and low-cost solution-processed deposition route to fabricate metal chalcogenide semiconductor thin films by using soluble precursors via a spin-coating technique. Surface morphology was directly influenced by the choice of organic solvents as well as the spin-coating sequences, thus affecting the electrical transport of the films. In the case of hybrid semiconductors, a conducting polymer was employed to help forming more uniform composite films.

This book was released on 2015 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic layer deposition (ALD) and molecular layer deposition (MLD) are advanced thin film coating techniques developed for deposition of inorganic and hybrid organic-inorganic films respectively. Decreasing device dimensions and increasing aspect ratios in semiconductor processing has motivated developments in ALD. The beginning of this thesis will cover study of new ALD chemistry for high dielectric constant Y 2 O3 . In addition, the feasibility of conducting low temperature ALD of TiN and TiAlN is explored using highly reactive hydrazine as a new nitrogen source. Developments of these ALD processes are important for the electronics industry. As the search for new materials with more advanced properties continues, attention has shifted toward exploring the synthesis of hierarchically nanostructured thin films. Such complex architectures can provide novel functions important to the development of state of the art devices for the electronics industry, catalysis, energy conversion and memory storage as a few examples. Therefore, the main focus of this thesis is on the growth, characterization, and post-processing of ALD and MLD films for fabrication of novel composite (nanostructured) thin films. Novel composite materials are created by annealing amorphous ALD oxide alloys in air and by heat treatment of hybrid organic-inorganic MLD films in inert atmosphere (pyrolysis). The synthesis of porous TiO2 or Al2 O3 supported V2 O5 for enhanced surface area catalysis was achieved by the annealing of inorganic TiVx Oy and AlV x Oy ALD films in air. The interplay between phase separation, surface energy difference, crystallization, and melting temperature of individual oxides were studied for their control of film morphology. In other work, a class of novel metal oxide-graphitic carbon composite thin films was produced by pyrolysis of MLD hybrid organic-inorganic films. For example, annealing in argon of titania based hybrid films enabled fabrication of thin films of intimately mixed TiO2 and nanographitized carbon. The graphitized carbon in the film was formed as a result of the removal of hydrogen by pyrolysis of the organic constituency of the MLD film. The presence of graphitic carbon allowed a 14 orders of magnitude increase in the electrical conductivity of the composite material compared fully oxidized rutile TiO2 .

Download or read book Microstructure Control in Organic and Hybrid Semiconductors and Its Impact on Device Performance written by Andrew Michael Zeidell and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the identification of anthracene as a semiconducting material in the 1960s, the field of organic electronics has seen a remarkable growth, with several breakthroughs that have changed our lives. Subsequent developments in chemical design have resulted in small molecule organic semiconductors with functionalized backbones, creating a new paradigm for organic electronics: solution processability. Solution processability increases the viability of novel and scalable deposition techniques, such as inkjet printing and spray deposition, but can often result in much more variable device performance due to the disordered microstructure in thin films deposited this way. Factors impacting the overall device performance are manifold and often interdependent: device design, solid-state packing, microstructure, and molecular structure all impact the electrical properties in intricate ways. The overarching goal of my PhD research was improving thin-film microstructure as a route to improve performance in both hybrid organic-inorganic and organic field-effect transistors (FETs). The FET is an excellent experimental tool to study charge carrier mobility in materials, as they enable the extraction of charge carrier mobilities from current-voltage characteristics of the device, with no approximations or assumptions being necessary. This research has specifically focused on using processing and post-processing techniques to control the degree of order in thin films, and characterizing the resulting structures using techniques such as X-ray diffraction, microscopy, and electrical measurements. This work encompasses quantitative studies on the use of solvent vapor annealing to improve thin-film morphology, and spans device design, fabrication, and characterization, as well as novel applications of OFETs in medical devices and large area sensors.
