摘要: Single-crystalline Cu7In3/CuIn0.8Ga0.2Se2 (CI/CIGS) core/shell nanowires are fabricated by pulsed laser deposition with Ni nanoparticles as catalyst. The CI/CIGS made up of single-crystalline CI cores surrounded CIGS shells. grown at a considerably low temperature (350°C ~ 450°C) vapor-liquid-solid mode combined vapor-solid mode. distribution density the increases increasing duration, and substrate determines lengths nanowires. U-V absorption spectra thin films without demonstrate that can remarkably enhance in spectrum range 300 to 900 nm. 61.46. + w; 61.41.e; 81.15.Fg; 81.07.b
