Abstract
Abstract Chalcopyrite Cu(In 0.8 Ga 0.2 )S 2 (CIGS) nanowires were synthesized by using a relatively simple and convenient electrospun process. From the reactions of CuCl, InCl 3, GaCl 3 and thiocarbamide as a precursor, semiconductor CIGS nanowires with diameter in the range of 60–80 nm were obtained for Polyvinylbutyral/CIGS precursor ratios of 40% at an applied voltage of 25 kV after annealing treatment at 600 °C for 3 h. A probable formation mechanism of chalcopyrite quaternary semiconductor nanowires is proposed based on a series of comparative experiments conducted under various reaction conditions.
