Book Description
Split and normal gate A1GaAs /GaAs MODFETs were fabricated along with the ohmic test structures and the Hall bar geometries. The DC characteristics of normal gate transistors were evaluated at room temperature and at 77K and the threshold voltages were extracted from the measurements and compared to the theoretical results. The performance of normal gate transistors was reasonable. The sheet carrier density and the mobility extracted from Hall measurements using the Hall bar geometry showed increase of carrier density with increasing gate voltage and an increase of mobility with increasing carrier density. The contact resistance obtained from the ohmic test structure was high and not uniform within the sample.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 36 (thesis year 1991) a total of 11,024 thesis titles from 23 Canadian and 161 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 36 reports theses submitted in 1991, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Organic Field Effect Transistors presents the state of the art in organic field effect transistors (OFETs), with a particular focus on the materials and techniques useful for making integrated circuits. The monograph begins with some general background on organic semiconductors, discusses the types of organic semiconductor materials suitable for making field effect transistors, the fabrication processes used to make integrated Circuits, and appropriate methods for measurement and modeling. Organic Field Effect Transistors is written as a basic introduction to the subject for practitioners. It will also be of interest to researchers looking for references and techniques that are not part of their subject area or routine. A synthetic organic chemist, for example, who is interested in making OFETs may use the book more as a device design and characterization reference. A thin film processing electrical engineer, on the other hand, may be interested in the book to learn about what types of electron carrying organic semiconductors may be worth trying and learning more about organic semiconductor physics.
