Ultra-thin conformal deposition of CuInS2 on ZnO nanowires by chemical spray pyrolysis

CuInS2 (CIS) was deposited on ZnO nanowires by a chemical spray pyrolysis (CSP) method, resulting in an ultra-thin, conformal CIS coating on ZnO forming ZnO–CIS core–shell structures. A high-resolution transmission electron microscope and elemental mapping showed the excellent quality of the coating...
