Journal ArticleDOI
Dispersion of polar optical phonons in wurtzite quantum wells
TL;DR: In this paper, the dispersion relations for polar optical phonon modes in wurtzite quantum wells (QW's) are obtained in the framework of the dielectric continuum model.
Journal ArticleDOI
Energy-dependent electron scattering via interaction with optical phonons in wurtzite crystals and quantum wells
Journal ArticleDOI
Generation and amplification of sub-THz coherent acoustic phonons under the drift of two-dimensional electrons
TL;DR: In this paper, it was shown that the electron drift can cause strong phonon amplification (generation) in high-frequency confined acoustic phonons by drifting electrons in a quantum well, and a general formula for the gain coefficient as a function of the phonon frequency and the structure parameters was obtained.
Journal ArticleDOI
