Semiconductor nanowires have been widely studied due to their unique properties like high aspect ratio and high carrier mobility. These unique properties make them a suitable candidate for various optical and electronic devices like photovoltaics, photodetectors, and field effect transistors. The surfaces of nanowires play an important role in the performance of these devices, because of their high surface to volume ratio. In this work, II-VI nanowires, grown via the high-temperature vapor liquid solid process, are treated following growth with solution phase reagents to control the chemical state of their surfaces. Fluorescence microscopy is used to demonstrate ligand binding on the nanowire surface, and these solution phase treatments are correlated with changes in electronic properties as determined from field effect transistor (FET) and photocurrent measurements.
