The preliminary result of laser-focused Cr atomic deposition for fabricating nanostructure
激光驻波场形成Cr原子沉积纳米光栅的初步实验研究

The technology of laser-focused atomic deposition can be used to develop the nanostrucrure transfer standard of length. When the frequency of laser standing wave is higher than the resonant frequency of atoms, the atoms will be focused on the wave node of the standing wave. The collimated Cr atoms are focused by a standing-wave laser field as they are deposited on a silicon substrate. Atomic force microscopy measurements shows a spacing of 215nm.
