Abstract (English):
Results of theoretical analyses of possibility of generations of periodic picosecond pulses of voltage are presented. This process is possible under condition of external electromagnetic radiation only. As an active element of such generator may be heterojunction in which the relaxation instability of electron concentration is developed. The possible variant of heterostructure and its static and time depended electric characteristics are demonstrated. Parameters of heterostructure and operating regimes can be select so that pulses of voltage will be in terahertz range.
