Abstract
We describe measurements of hot-electron dynamics in superlattices under flat band conditions and superlattices in a uniform electric field. Under flat band conditions we show that carriers in high-lying minibands can propagate for several superlattice periods without scattering and can be described within miniband pictures of transport. In a uniform electric field, the minibands immediately break down into localized states, and we show how these states participate in conduction.

Bearing in mind that the analyzer collects only those electrons whose energy exceeds the barrier height, it is easy to see that the number of electrons of a given energy is related to ∂ I c / ∂V bc , which we define to be n(Є).
Strictly the excitation is a coupled plasmon-optic phonon mode with slightly higher energy.
