80 페이지 - The energy difference between the top of the valence band and the bottom of the conduction band is called the band gap.
35 페이지 - A. OBJECTIVE This project is devoted to the studies of the microwave region of acoustic wave amplification in piezoelectric semiconductors. The first experiments on this project were reported by Hutson, McFee, and White, wherein they demonstrated that electrons drifting through cadmium sulphide could give up energy to the acoustic waves if the electrons were drifting faster than the velocity of sound. Both the drifting carriers and the elastic...
92 페이지 - ... provide the preferred solution to a considerable number of problems which will arise from now onwards in the exploration of space . . . The examination is not in terms of current performances of masers already developed but in terms of those which we can reasonably hope to achieve in the near future. GENERATION OF ACOUSTIC SIGNALS IN LIQUIDS BY RUBY LASER-INDUCED THERMAL STRESS TRANSIENTS (EFFECT OF ACOUSTIC BOUNDARY CONDITION ON IMPULSE SHAPE— E/T) EF Carome, et al.
75 페이지 - IN: INTERSTELLAR COMMUNICATION. Edited by AGW Cameron. New York and Amsterdam. WA Benjamin, Inc., 1963, p.
25 페이지 - Law does not apply (in its usual form) to the angle of transmission In addition, relations are developed that appear to be useful and convenient for a practical calculation of the appropriate angle Also, it is demonstrated that the usual Doppler-shift expression must be modified to account for...
24 페이지 - Results are presented of tests on star observations, on photomultipher performance, and on the effects of the atmos phere on laser propagation The study supported the belief that optical communication has the potential to replace radio and to perform unique functions in many space situations Certain methods are proposed to overcome the restriction of receivers to...
