Based on theory of wave particle duality,the principal and method about making random nano-pattern by Ne atom hologram are studied. This technology can make up the disadvantage of only being able to make the periodic nano-pattern such as the single line or dot etc.when using laser gradient field to control atoms' movement to accumulate on the silicon slice.Analyzing the difference of atom hologram and optical hologram, we point out that only the laser cooling atoms can satisfy the coherent and diffract conditions required by the hologram technology. A piece of Ne atom computer generated hologram (CGH) with Lohmann Ⅲ coding is designed and a experiment system of making random nano-pattern by controlling Ne atom beam is presented.
A cold metastable neon atomic beam was manipulated with a reflective amplitude hologram that was encoded on a silicon surface. A black-and-white pattern of atoms was reconstructed on a microchannel plate detector. The hologram used the enhanced quantum reflection developed by authors and was made of a two-dimensional array of rectangular low and high reflective cells. The surface of the high reflective cell was composed of regularly spaced roof-shaped ridges, while the low reflective cell was simply a flat surface. The hologram was the first demonstration of reflective atom-optical elements that used universal interaction between a neutral atom and solid surface.
