Low-Temperature Micro-PL Measurements ofInAs Binary Quantum Dots on GaAsSubstrate Nan Thidar Chit Swe Suraprapapich, Suwaree Wissawinthanon, Chanin Panyakeow, Somsak Tu, Charles W. Arakawa, Yasuhiko Optical properties of InAs binary quantum dot(bi-QD) molecules grown on the (001) GaAs substrate were measured by means of temperature- andexcitation-power-dependent photoluminescence (PL)spectroscopy. It was observed that the shape and peak position of the PL spectra changed with the temperature and with the excitation power. It wa salso found that the linear polarization degree of thebi-QD PL signal changed with temperature. The temperature-dependent PL described that the linear polarization degree of bi-QDs is closely related to the carrier dynamics. 2008 http://hdl.handle.net/20.500.12678/0000002493 https://meral.edu.mm/records/2493
