Ea. Gel'Vich et al., A resonant-tunneling transit-time diode for the terahertz frequency range employing transitions between quantum states in a double-barrier injector, TECH PHYS L, 26(7), 2000, pp. 544-546
The possibility of considerably reducing the start-up current of a coherent
resonant-tunneling transit-time diode operating in the terahertz range is
demonstrated. The proposed scheme relies on resonance electron transitions
in a double-barrier injector. (C) 2000 MAIK "Nauka/Interperiodica".
