In situ characterization of kinetics and mass transport of PbSe nanowire growth via LS and VLS mechanisms

摘要

We grew binary PbSe nanowires in an in situ gas-heating cell in a transmission electron microscope and elucidated species dependent mass transport pathways and key correlations among supersaturation, nucleation, and growth kinetics, thereby enabling morphological and compositional control of nanowires with tailored properties.
