It was found that large scale single crystal ttf m - nbp film can be obtained by this method . atomic resolution surface images were observed both with atomic force microscope and scanning tunneling microscope . high density data storage was realized by applying voltage pulses between the stm tip and the substrate 用原子力显微镜afm和扫描隧道显微镜stm都观察到了ttf m - nbp薄膜表面的原子级分辨像。通过stm针尖施加脉冲电压在ttf m - nbp薄膜上实现了纳米级的信息存储,最小记录点直径约为1 . 2nm 。
