摘要

A force sensor based on a zinc oxide tetrapod is provided in this paper. The performance of the device was fully investigated by atomic force microscopy. Tuning Schottky barrier height by Piezo-phototronic effect leads to the increasing sensitivity of sensor from 0.17 A/N to 2.05 A/N under forward bias. The possible mechanisms have been proposed and discussed.
