摘    要:提出了原子力/光子扫描隧道显微镜(AF/PSTM)系统的关键部分——双功能弯曲光纤探针的制作方法.采用热拉伸与动态、静态两步化学腐蚀相结合的方法制作出AF/PSTM弯曲光纤探针,弯曲角度约为150°,尖端曲率半径优于100nm,锥角范围为60°—90°.将这种双功能弯曲光纤探针应用在新研制的AF/PSTM系统上,同时获得了样品的光学与形貌图像,实现了图像分解. 关键词: 原子力/光子扫描隧道显微镜 光纤探针 热拉伸 化学腐蚀

关 键 词:原子力/光子扫描隧道显微镜  光纤探针  热拉伸  化学腐蚀

Abstract:In this paper,a fabrication method for the bi-functional bend optical fiber probe which is the key element of atomic force/photon scanning tunnel microscope (AF/PSTM)system,is described.The heated pulling combined with dynamic/static two-s teps chemical etching method is proposed and developed.Using this method,we have made the AF/PSTM bend optical fibre probe.The bend angle of the probe is about 150 degrees;the radius of curvature at the top end is better than 100nm;the cone angle varies from 60 to 90 degrees.The bi-functional bend optical fiber probe i s used in our newly developed AF/PSTM system.The optical and topographic images are obtained simultaneously and the image separation is realized.
Keywords:AF/PSTM  optical fiber probe  heated pulling  chemical etching
