Abstract
Local surface chemistry and nonlocal deposition modes in the photodeposition of silica films from silane and oxygen mixtures have been studied by surface-sensitive infrared vibrational spectroscopy. The two-step surface reaction leading to the photoinduced chemisorption of silane and oxygen is identified. Dynamic roughening of the growth front is shown to occur with a characteristic exponent of 0.340.05, fitting the Kardar-Parisi-Zhang model.
