Abstract

Transmission electron microscopy and photoluminescence data are used to show that a s i n g l eGaAsquantum well (L z ≊70 Å) confined by Al x′Ga1−x′As (x′∼0.3) layers can, via low‐temperature (600 °C) Zndiffusion, be interdiffused (‘‘absorbed’’) into the confining layers (impurity‐assisted Al‐Ga interdiffusion) and be shifted to higher gap (x=0→x′∼0.3) without damaging the crystal or ruining its capability to operate as a continuous 300‐K low threshold photopumped laser.
