Effects of low-temperature capping on the optical properties of GaAs/AlGaAs quantum wells
<p>Abstract</p> <p>We study the effects of low-temperature capping (200-450°C) on the optical properties of GaAs/AlGaAs quantum wells. Photoluminescence measurements clearly show the formation of abundant nonradiative recombination centers in an AlGaAs capping layer grown...
