Polar-optical-mode scattering for an ideal quantum-well heterostructure

Abstract

It is pointed out that approximations, such as have been proposed, in the normal-direction form factor which enters into the basic lattice scattering rates for two-dimensional heterolayer transport are not necessitated by the singularities of this form factor in the ideal "quantum-well" case. The H(Q) function which actually governs the polar-optical-mode scattering rates in this case is not singular. It is given as an analytical function of the two-dimensional transfer wave vector and is displayed in a numerical plot. © 1984 The American Physical Society.
