ADVANCED CONCEPTS OF MICROWAVE GENERATION AND CONTROL IN SOLIDS.

Abstract

Injection locking of LSA oscillators was observed and a low frequency bias circuit oscillation was also investigated. Power-frequency scaling studies of LSA diodes are discussed. Work on high cycle LSA along thin slabs of gallium arsenide is also reported. A hybrid mode in gallium arsenide characterized by having the domain formation time of the same order of magnitude as the active portion of the r-f period is discussed. Studies of the electronic characteristics of a quenched mode Gunn effect oscillator was completed. Large signal i-v characteristics of avalanche p-n junction were investigated. Studies of the effect of space charge on the efficiency of avalanche diodes are described. Avalanche transit-time phenomena in p-n InSb diodes are also discussed. The results of studies of the properties of very short samples of InSb in high electric fields are also reviewed. Results of a study of nonlinearities of semiconductor avalanches are reported. Work on materials research is described including studies of epitaxial growth of gallium arsenide and solution grown epitaxial layers of gallium arsenide are also reported. Progress on ion implantation work in silicon is discussed. Highly magnified field emission patterns of the emission from germanium whiskers were obtained. The results of microwave switching experiments using laser generated carbon plasmas are reported.
