“…With the framework of DC model, [5][6][7][8][9][10][11][12] using the boundary conditions 7-11 at the z = z j interface successively, the dispersion relation of IO phonons can be obtained by a 2n × 2n determinant in Refs. [8,14].…”

Based on the dielectric continuum model and modified random-element isodisplacement model, the ternary mixed crystal effects on interface optical phonon and electron-interface optical coupling in GaN/AlxGa1-xN quantum wells are studied in a fully numerical manner. When the aluminium concentration in the range (0.03, 0.13), there exist two branches of interface optical phonons in high frequency range. When the aluminium concentration in the range (0.13, 1.00), there are four branches of interface optical phonons in high and low frequency range. With the increase of aluminium concentration, the frequencies of interface optical phonon almost change linearly. The electron-phonon couplings also almost linearly vary with aluminium concentration in high frequency range. But in low frequency range, the electron-phonon coupling indicate nonlinear changes with increasing aluminium concentration.

“…The confined optical phonons and their electron-phonon interaction were also researched in Refs. [9][10]. However, most of the work published so far focused on optical phonons in QWs composed of binary wurtzite crystal, the optical phonons in wurtzite QWs consisted of mixed crystal have not been investigate in detail.…”
