简单评述了在电荷载流子漂移情况下半导体内超声放大和声学噪声发生现象的研究结果。列举了所研制的实验装置的特性。讨论了它们在无线电电子学中应用的某些前景。近年来,发现了一系列立足于固体内超声波同由基波激励的各种形式之间相互作用的新现象:电子-声子相互作用,自旋-声子相互作用等。这些现象的发现大大扩展了无线电电子学中利用超声来制造各种新器件的可能性,如:具有延迟信号放大的有源超声延迟线,固体行波管型放大器,声子-声子脉降,能均匀可调 The results of studies on the ultrasonic amplification and acoustic noise in semiconductors under the condition of charge carrier drift are briefly reviewed. The characteristics of the experimental device developed are listed. Discussed some of their prospects for use in radio electronics. In recent years, a series of new phenomena based on the interaction between solid-state ultrasonic waves and fundamental waves have been found: electron-phonon interaction and spin-phonon interaction. The discovery of these phenomena greatly expands the possibilities of using ultrasound to manufacture various new devices in radio electronics such as active ultrasound delay lines with delayed signal amplification, solid traveling wave tube amplifiers, phonon-phonon pulse-drop , Can be evenly adjustable
