Abstract
Phenomena of interaction in the direction perpendicular to the layer planes, for hot electrons in heterolayer structures such as may be grown by molecular beam epitaxy, are discussed. In particular, energy transfer between electrons in neighboring heterolayers, due to mutual coulomb scattering, and escape of electrons from a heterolayer, due to phonon scattering processes, are analyzed; and it is shown that substantial rates are possible. © 1983.
