2011
IEEE Journal of Quantum Electronics
Preserved Fulltext
A-plane InGaN/GaN multiple-quantum wells (MQWs) were grown on a series of nanorod epitaxial lateral overgrowth (NRELOG) templates with varied nanorod depth. ...
Optical properties of these samples were investigated by excitation power and temperature-dependent photoluminescence (PL). ...
Therefore, in the paper, we deposit InGaN/GaN multiple quantum wells (MQWs) on the high crystal quality NRELOG a-plane GaN templates and investigated their optical properties as well as internal quantum ...
