Abstract
Scanning tunneling microscopy (STM) and transmission electron microscopy (TEM) were used to explore and measure the gas-surface chemical reactions on a Si(100) surface. It aimed to measure the surface morphology at the formation of silicon nanodots with uniform sizes. Silicon nitride islands were formed on the Si(100) surface through an exposure of N2 gas at temperatures between 700 and 800 °C. A very high surface density of 5 nm size silicon dots with full width at half maximum (FWHM) of 2.5 nm was reproducibly obtained, suggesting a simple but very efficient way of fabricating silicon nanodots.
