摘要：

A detailed study of the energy and momentum relaxation together with the determination of the dominant scattering mechanisms in the wide band gap III-N semiconductor materials are crucial for obtaining a comprehensive understanding of the carrier dynamics, especially at high operating electric fields. In this work we study a AlGaN/GaN quantum dots. The energy loss rate of quantum dot are calculated as a function of the external controllable parameters electrons density, quantum dot size and lattice temperature for the interaction of the charge carriers with bulk acoustic (deformation potential and piezoelectric scattering) and optical phonons.
