Abstract : The research program is concerned with new techniques for microwave signal generation. The emphasis of the investigation is on studies of active microwave effects in bulk semiconductors and on physical electronic phenomena. Specifically the study areas include the domain and Limited Space charge Accumulation (LSA) modes of the Gunn-Effect, Impact Avalanche and Transit Time (IMPATT) diodes, and microwave semiconductor materials properties. The research is being undertaken to further the understanding of the physical mechanisms and processes which are involved and to obtain information of use in the design of improved microwave sources. The work accomplished during the ninth quarterly period is discussed in this report. (Author)
