We have newly proposed a novel growth method for high quality CuGaSe2 (CGS) thin films in which ionized Ga was used as new source material. The films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman spectroscopy. The grain size enlargement was successfully demonstrated by using ionized Ga precursors. The experiments revealed that the local heating caused...
The low temperature synthesis of single-walled carbon nanotubes (CNTs) on a Si substrate has been reported. Single-walled CNTs were grown from a C 2 H 2 and H 2 mixture by a hot-filament enhanced CVD method using a carbon filament. The catalyst was silica-supported iron-cobalt prepared by sol-gel method. We observed the influence of the catalyst material, C 2 H ...
