摘要
ZnCdSe/ZnSe multiple quantum-well(MQW) structures were grown by MBE on ZnSe(0 0 1) substrates prepared by seeded chemical-vapour transport (SCVT) in hydrogen. Scanning force microscopy (SFM) analysis of these structures was performed. A method for the preparation of the substrate surface was found that resulted in a decrease of the root-mean-square (RMS) roughness of the MQW structure surfaces, down to 1 nm. For these structures intense cathodoluminescence (CL) from the QWs was observed. By e-beam pumping a microcavity, pulse lasing was achieved at room temperature(RT). (C) 1998 Elsevier Science B.V.
