On a native graphite surface, 15 nm-thick solid-state nanogears are nanofabricated with a 30 nm outer diameter and six teeth. The nanogears are manipulated one at a time by the tip of an atomic force microscope using the sample stage displacements for the manipulation and recording of the corresponding manipulation signals. For step heights below 3.0 nm, nanogears are manipulated up and down native graphite surface step edges. In the absence of a central shaft per nanogear, gearing between nanogears is limited to a few 1/12 turns for six teeth. When the graphite step is higher than 3 nm, a rack-and-pinion mechanism was constructed along the edge with a 90 nm nanogear pinion.
在天然石墨表面，通过纳米加工制造出外径为30纳米、有六个齿的15纳米厚的固态纳米齿轮。使用样品台位移通过原子力显微镜的针尖一次操纵一个纳米齿轮，并记录相应的操纵信号。对于低于3.0纳米的台阶高度，纳米齿轮在天然石墨表面台阶边缘上下移动。由于每个纳米齿轮没有中心轴，六个齿的纳米齿轮之间的传动比限制在几1/12转。当石墨台阶高于3纳米时，沿着边缘用一个90纳米的纳米齿轮小齿轮构建了一个齿条齿轮机构。
