dc.description.abstractCarrier recombination in lateral composition modulation (LCM) GaInP was probed in detail using time-resolved photoluminescence (TR-PL) and transmission electron microscopy (TEM). Upon SiO2 passivation, the time-transient decay of the PL peak was slower, and carrier lifetime was significantly enhanced from 25 to 230 ps for passivated LCM GaInP in comparison with that of bulk GaInP. This is due to the suppressed surface recombination of the irregular and wavy surface of LCM GaInP observed by TEM. Temperature-dependent TR-PL also showed a large decrease in carrier lifetime with an increase in temperature, indicating the dominance of Shockley–Read–Hall recombination due to the nonperiodicity of the LCM structure.
