In this study, carbon nanotubes (CNTs) were synthesized on a catalyst of zinc oxide (ZnO) nanorods prepared with a hydrothermal process. The surface morphology of the CNTs was studied with scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and the structural properties and chemical compositions of the CNTs were studied with Raman spectroscopy and energy dispersive spectrometer...
Silicon and its related alloys deposited by catalytic chemical vapor deposition (Cat-CVD), takes place upon thermo-catalytic decomposition of the reactant gases, i.e. silane (SiH4) and hydrogen (H2), at the surface of a hot filament. Tantalum (Ta) has been used as catalyst which resulted with better controllability from amorphous to crystalline-phase transition. Process for depositing hydrogenated...
