Abstract

The single crystalline CdS nanobelts were synthesized by an improved vapor-liquid-solid (VLS) process. Field emission measurements show that the nanostructures have a low turn-on field of 3.7 V&m^-1 at a current density of 10 μA cm^-1, a low threshold field of 9.3 V μm cm^-1 and a high enhancement factor of 1298. When assembled into nanoscale visible light photodetectors, the CdS nanobelts showed good sensitivity and wavelength selectivity. The results imply that the present CdS nanobelts are excellent candidates for applications in high-performance field emitters and photodetectors.
