Working mechanism for piezotronic devices with two ends fixed with electrodes on a flexible substrate. This asymmetric tuning of the Schottky barrier height is the piezotronic effect.
Piezotronics effect is using the piezoelectric potential (piezopotential) created in materials with piezoelectricity as a “gate” voltage to tune/control the charge carrier transport properties for fabricating new devices.
Neil A Downie showed how simple it was to build simple demonstrations on a macro-scale using a sandwich of piezoelectric material and carbon piezoresistive material to make an FET-like amplifying device and put it in a book of science projects for students in 2006.[1]
The fundamental principle of piezotronics was introduced by Prof. Zhong Lin Wang at Georgia Institute of Technology in 2007.[2]
From 2006, a series of electronic devices have been demonstrated based on this effect, including piezopotential gated field-effect transistor,[3] piezopotential gated diode,[4] strain sensors,[5] force/flow sensors,[6] hybrid field-effect transistor,[7] piezotronic logic gates,[8] electromechanical memories,[9] etc.
Piezotronic devices are regarded as a new semiconductor-device category. Piezotronics is likely to have important applications in sensor, human-silicon technology interfacing, MEMS, nanorobotics and active flexible electronics.
