Na. Zakhleniuk et al., Interaction of non-equilibrium electrons with phonons in bulk GaN and GaN/AlGaN quantum wells, PHYSICA B, 263, 1999, pp. 549-552
The analytical theory of non-equilibrium electrons interacting with deforma
tion acoustic, piezoacoustic and polar optical phonons in GaN-based quantum
wells and bulk GaN is developed taking into account multi-subband populati
on. The new distribution functions thus obtained are used for the calculati
on of the electric field dependence of the electron mobility and the averag
e electron kinetic energy. The theory provides a self-consistent transition
from the two-dimensional to the three-dimensional regimes of electron tran
sport in quantum wells with increasing external electric field, (C) 1999 El
