| dc.description.abstract | We report an investigation on the efect of oxygen fow rate on the structural and optical
properties of zinc oxide thin flms prepared by RF magnetron sputtering. The structural
measurements were carried using grazing incidence X-ray difraction, atomic force microscopy and Raman spectroscopy. The role of oxygen partial pressure on the crystallinity, the
surface morphology and vibrational modes has been established. The optical properties of
the flms were investigated using FR-Basic-VIS/NIR ftted with FR-Monitor software for
flm thickness, refractive index and color determination. The flm thickness is observed to
increase when oxygen is introduced at 4 sccm but eventual decrease with increase in the
fow rate an indication of initial increase in rate of deposition followed by reduction. Elaborate explanations of these trends are provided | en_US |
