This book was released on 2008 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Due to its unique physical properties, gallium nitride (GaN) is under intense investigation for the development of transistors for high power, high frequency and high temperature applications. The majority of existing literature addresses field effect transistors. This dissertation addresses a wide spectrum of materials and device studies required for the development of GaN-based heterojunction bipolar transistors (HBTs). The investigated structure has the emitter region based on n-Al x Ga 1-x N alloys, while the base and collector were based on p-In y Ga 1-y N and n-GaN, respectively. The growth and doping of the various layers of the transistor structure, on sapphire substrate, GaN-templates and free standing GaN substrates are addressed. Particular emphasis was placed on the p-type doping of the AlGaN and InGaN alloys with magnesium, both doping of bulk films as well as superlattices. The experimental results were compared with theoretical predictions of a self-consistent solution to the one-dimensional poisson and schrodinger equations. A hole concentration for p-InGaN of 9x10 18 CM -3 was obtained, which is the highest value published. The device aspect of this research addressed issues related to the development of novel methods of selective growth by molecular beam epitaxy (MBE) of the emitter onto the base. This was found to be necessary to avoid damage of the base during mesa etching. The final product of this research was the fabrication and DC characterization of HBT devices. This included various lithography, metallization, etching and annealing steps. The devices were evaluated under common base and common emitter configurations and the best result obtained was a room temperature gain of 59.

Available in PDF, EPUB and Kindle. Book excerpt: Gallium Arsenide technology has come of age. GaAs integrated circuits are available today as gate arrays with an operating speed in excess of one Gigabits per second. Special purpose GaAs circuits are used in optical fiber digital communications systems for the purpose of regeneration, multiplexing and switching of the optical signals. As advances in fabrication and packaging techniques are made, the operat ing speed will further increase and the cost of production will reach a point where large scale application of GaAs circuits will be economical in these and other systems where speed is paramount. This book is written for students and engineers who wish to enter into this new field of electronics for the first time and who wish to embark on a serious study of the subject of GaAs circuit design. No prior knowledge of GaAs technology is assumed though some previous experience with MOS circuit design will be helpful. A good part of the book is devoted to circuit analysis, to the extent that is possible for non linear circuits. The circuit model of the GaAs transistor is derived from first principles and analytic formulas useful in predicting the approxi mate circuit performance are also derived. Computer simulation is used throughout the book to show the expected performance and to study the effects of parameter variations.
