Abstract

The idea of a laser operating on the basis of "cold" ballistic electrons with E ≲ 0.1 ev was discussed in Ref. ¹. It was shown that electrons with an energy below the height of the potential barrier of the superlattice, U₀, would undergo transition between quasibands. The possibility of generating "hot" ballistic electrons, with E = 0.1-0.3 ev, injected into Ga As, was first demonstrated in Refs. 2 and 3.
