Carrier dynamics and recombination mechanisms in InP twinning superlattice nanowires

Yuan, Xiaoming; Liu, Kunwu; Skalsky, Stefan; Parkinson, Patrick; Fang, Long; He, Jun; Tan, Hark Hoe; Jagadish, Chennupati


Nominal dopant-free zinc blende twinning superlattice InP nanowires have been grown with high crystal-quality and taper-free morphology. Here, we demonstrate its superior optical performance and clarify the different carrier recombination mechanisms at different temperatures using a time resolved photoluminescence study. The existence of regular twin planes and lateral overgrowth do not significantly increase the defect density. At room temperature, the as-grown InP nanowires have a strong...[Show more]
