[交流] 做纳米的虫子们注意了，大牛王中林的 Nanogenerators！！

做纳米的虫子们注意了，大牛王中林的 Nanogenerators！！

14 APRIL 2006 VOL 312 SCIENCE
Abstract：

We have converted nanoscale mechanical energy into electrical energy by means of piezoelectric
zinc oxide nanowire (NW) arrays. The aligned NWs are deflected with a conductive atomic force
microscope tip in contact mode. The coupling of piezoelectric and semiconducting properties in zinc
oxide creates a strain field and charge separation across the NW as a result of its bending. The
rectifying characteristic of the Schottky barrier formed between the metal tip and the NW leads to
electrical current generation. The efficiency of the NW-based piezoelectric power generator is
estimated to be 17 to 30%. This approach has the potential of converting mechanical, vibrational,
and/or hydraulic energy into electricity for powering nanodevices.
