Vashista, R. K. Kalia and R. F. Bishop WebThe characteristics of phonon growth in a degenerate semiconductor at low lattice temperatures have been studied for inelastic interaction of non-equilibrium electrons with the intravalley acoustic phonons. The energy of the phonon and the full form of the phonon distribution are taken into account. The results reveal significant changes in the growth …

What is Degenerate Semiconductor - Definition

WebMay 15, 2012 · A degenerated semiconductor is a semiconductor with such a high carrier concentration that the material starts to act more like a metal. Since generated semiconductors are highly conductive, they are necessary in a variety of applications in optoelectronic devices [1].
