Dr. Anderson et al., Polar-optical phonon-limited transport in degenerate GaN-based quantum wells - art. no. 245313, PHYS REV B, 6324(24), 2001, pp. 5313
A theory of polar-optical phonon-limited electron transport in GaN-based qu
antum wells is developed within the Boltzmann equation approach. The linear
ized Boltzmann equation is solved for a degenerate two-dimensional electron
system using a ladder technique, enabling evaluations of the effective mom
entum relaxation time and the low-field electron mobility to be carried out
. Variations of the effective momentum relaxation time with the well width,
electron energy, lattice temperature, and electron density are explored in
these heterostructures. The corresponding mobility is then evaluated and i
ts variations with the well width, lattice temperature, and electron densit
y displayed. Comparison is made, where appropriate, with the results emergi
ng from the application of a low-energy approximation.
