Single-Crystalline Sb_2Se_3 Nanowires for High-Performance Field Emitters and Photodetectors

摘要

Group V-VI binary chalcogenides, which are highly anisotropic semiconductors crystallizing in layered structures with layers in parallel to the growth direction, have attracted considerable attention due to their importance in basic scientific research and potential applications in TV cameras with photoconducting targets, thermoelectric and optoelectronic devices, and IR spectroscopy. Among them, Sb_2Se_3, a direct narrow-bandgap semiconductor with a good chemical stability and excellent photovoltaic properties, reveals a particular promise for solar selective and decorative coatings, and optical, and thermoelectric cooling devices.
