[18p-234B-10] Photon upconversion via submonolayer InAs structures
Keywords:Quantum Dot, submonolayer growth
InAs / GaAs submonolayer (SML) growth has attracted attention for the growth of quantum structures such as those applied for solar cells. Samples with different SML sequences are prepared by MBE and studied by RHEED, AFM and PL. Here, we prepared structures that contain both SML layers and quantum wells to elucidate the carrier dynamics of up-converted PL.
