Neutron Irradiation Effect in Two-Dimensional Electron Gas of AlGaN/GaN Heterostructures

摘要

@@ AlGaN/GaN heterostructures have been irradiated by neutrons with different fluences and characterized by means of temperature-dependent Hall measurements and Micro-Raman scattering techniques.It is found that the carrier mobility of two-dimensional electron gas (2DEG) is very sensitive to neutrons.
