MOLECULAR TUNABLE AMPLIFIERS.
Abstract
The contract effort is directed to research and development on a solid state tunable amplifier contained in a single crystal structure without employment of conventional electronic components. Semiconductor germanium delay lines were made and tested. Analysis suggests that optimum delay line amplifiers can be made in p-type silicon and p-type germanium and these devices will be examined during the next contract period. Conclusions drawn from the work indicate maximum usefulness for the delay line amplifier in frequency range from 50 kcps to 150 kcps. It is interesting to note that the delay line amplifier makes direct use of the minority carrier delay phenomena in a semiconductor for tuning rather than miniaturization of a traditional RC time constant circuit. The success of the stimulated emission amplifier (SEASER) cannot be predicted until fundamental excitation lifetimes are measured experimentally as discussed in the report. (Author)
