Low Temperature Photoluminescence (PL) from High Electron Mobility Transistors (HEMTs)
Abstract
The purpose of this report is to investigate the low temperature Photoluminescence (PL) from High Electron Mobility Transistor (HEMT) structures that have been modified by proton irradiation. The samples are aluminum gallium nitride (AlGaN)/gallium nitride (GaN) and indium aluminum nitride (InAlN)/GaN HEMT structures. These samples were cooled to 13 K and excited with Continuous Wave (CW) lasers at 325 and 244 nanometers to look for PL originating from a Two-Dimensional Electron Gas (2DEG).
