摘要: A transverse piezoelectric field-effect transistor (TP-FET) based on single ZnO nanobelts has been fabricated a metallic graphite substrate in an atomic force microscope (AFM). The source-to-drain current of the TP-FET was found to decrease with increasing loading under positive bias due carrier-trapping effect and creation charge-depletion zone. This can be applied as force/pressure sensor for measuring nanoNewton forces ranged from 0 700 nN.
