## Abstract Microβelectroluminescence measurements were performed on multiple quantum well samples grown on sapphire and GaN substrates with emission wavelength 495βnm. Meandering structures were found both in intensity and peak energy. Areas with higher emission intensity had lower energy, which i
We have investigated the influence of the TEGa flow on the optical and structural properties of InGaN/GaN multiple quantum wells (MQWs) with an indium composition around 20%. The samples with five-pairs InGaN/GaN MQWs were grown on sapphire substrates by metalorganic chemical vapor deposition. Photo
