【Abstract】 The basic principle and experimental system design for applying laser focused atomic beams technique to fabricate nano patterns are introduced. The focusing properties and aberrations of standing wave (SW) lens for a thermal atomic beam are studied through numerical simulation. The result shows that this type of SW lens can be used for atomic nanofabrication (ANF). The FWHM of the line width deposited on the substrate at the focal plane of the thermal atomic beam is about 10nm. The experimental set up and primary results are given.更多还原
