Abstract
In this paper a ballistic transport of current carriers with special dispersion relation ε(px) across a thin doped base of the n + nn + or p+pp+ - diode is considered (px is a component of crystal momentum p in the current direction). A distinguished feature of the ε(px)- relation consists in the presence of some region in the p- space where effective mass of the carriers (∂ 2 ε /∂px 2y)-1 is negative. Among possible mechanisms of realization of the required dispersion relation we turn attention to such of them which can be described by matrix Hamiltonian: H 11 = ε(1) (p), H 22 = ε (2)(p), H12 = H21=δ,
