Photoreflectance spectroscopy results are reported for InAs/GaAs self-organ
ised quantum dots grown by low-pressure MOCVD. Quantum dot-related optical
transitions have been observed for the first time at room temperature. Good
agreement between experiment and theory based on a recent 8-band k-p theor
y has been obtained. (C) 1999 Elsevier Science Ltd. All rights reserved.
