Creation of nano-sized spaces in carbon materials by oxidation and their characterization under STM
Source abstract
Abstract
Abstract Quantitative characterization of nano-sized spaces by STM techniques was discussed. Nano-sized spaces were introduced by oxidation; either oxygen plasma on perfect graphite structure or air oxidation on the surface of carbon spheres with highly disordered structure. By the irradiation of oxygen plasma at room temperature, nano-sized structural defects (missing carbon atoms, vacancies) were introduced in graphite layer plane. The increase in input power led to the increases in both density and size of defects, but that in irradiation time with a constant power resulted mostly in the increase of defect density, a little effect on the size of defects. By the oxidation of carbon spheres with disordered structure in static air at 400°C, spaces in the size range of 0.5–1.35 nm increased, though large spaces with the size of >2.2 nm were formed. The characterization of nano-sized spaces by STM with the aid of image processing and statistical analysis was shown to be effective.
