中文摘要：

通过对在Si（111）-7×7表面上生长的Pb岛施加脉冲偏压,Pb岛受到触发而自发再生长。通过调节操纵参数（如脉冲电压的大小和时间）,岛的高度及形状可以较精确地控制。用这种方法,我们可以制造出一些特定形状的纳米结构,例如中空和半中空的纳米阱等,还可以在更大尺度（微米）上进一步构建由这些纳米结构单元构成的图案。在纳米结构的构建过程中,还观察到了量子效应对薄膜生长的影响。

英文摘要：

We reported a novel method of constructing nanostructures with atomic layer precision, by manipulating a large number of atoms using a scanning tunneling microscope. By applying pulse voltages on the as-grown Pb island on Si（ 111 ）-7 × 7 surface, the target island can be triggered to re-grow simultaneously, and the height and shape of the target island were precisely controllable through regulating the manipulation parameters. Artificial nanostructures, such as nanomesas, center-full-hollowed and half-hollowed nanowells, as well as largescale nanostructure patterns coued be created by this way. Quantum size effects on the growth of thin films were observed and discussed.
