摘要
We have investigated spectroscopically the emergence of gain in InGaN/GaN quantum well diodes under high current injection (>kA/cm2). The spectral characteristics suggest that the electronic states responsible for blue laser action in this material are strongly influenced by the presence of microscopic crystalline disorder.
