Water Adsorption on Oxygen Passivated Silicon Nanoparticles
Water adsorption on silicon (Si) nanoparticles (NPs) passivated with oxygen are studied. These NPs show optical absorption below 1 μm. Temperature dependent change in surface opacity of Si NPs film is observed within a range of 30 to 100 °C. This is attributed to Si NPs which forms agglomerates and adsorbs water in nanopores. The agglomerates are of 200 nm while the NPs are 1.0 ± 0.3 nm in diameter. The change in surface opacity due to water adsorption and desorption with temperature is repeatable. The temperature dependent Fourier transform infrared spectroscopy, environmental scanning electron microscopy, and scanning tunneling microscopy measurements confirms that the water adsorbed around the NPs is largely in liquid phase.
