    • Our work demonstrates a unique device design to investigate the piezo-gating effect on ZnO and MgZnO thin-film. Herein, we have grown highly c axis oriented crystalline ZnO and MgZnO thin-film on top of SiO2/Si substrate via RF sputtering deposition method. In order to investigate the piezo-gating effect, we have used top and bottom electrodes. It is observed that the presence of an external compressive force induces piezopotential, which affects the channel behavior by a redistributing internal charge carrier. We have observed nearly ±7% changes in current ratio with and without external force for ZnO thin-film and around 11% for MgZnO, which can be attributed to piezo-gating effect. To validate the experimental results, we have carried out COMSOL Multiphysics Simulations. In simulation, we have carried out theoretical calculation on ideal ZnO and also get a similar change in current around ±7%. We have also achieved a higher gauge factor for piezotronic transistor around 10x103, due to higher current response and low strain value.
