摘要：
A strong and narrow photoluminescence (PL) signal with a full-width at half-maximum of 34 meV emitting at 1.3 mum at room temperature has been obtained from InAsN quantum dots (QD) on GaAs. The PL yield of the 1.3 mum peak at room temperature remains at 8% of the value at 10 K and the carrier lifetime at 10 K is measured to be 600 ps. We believe these values indicate that the gown InAsN QDs are of high crystal quality (C) 2002 Elsevier Science B.V. All rights reserved.
