Be掺杂对InGaAsN/GaAs量子阱性能的提高
Improvement of Properties of GaAs-based Dilute Nitrides by Beryllium Doping
摘要
Abstract
Heavily doping beryllium in the InGaAsN/GaAs quantum well (QW) can improve the optical properties significantly, while the emission wavelength is red-shifted.The X-ray diffraction (XRD) rocking curves provide clear-cut evidence that the doping of Be suppresses the strain relaxation in InGaAsN(Be)/GaAs QW during thermal annealing.An obvious XRD rocking curve peak shift of no-Be QW diffraction towards GaAs substrate peak before and after annealing was observed, while the shift for the Be-doped QW was much smaller than undoped QW.关键词
