The Effect of Applied Pressure on the Nonlinear Behavior of ZnO Based Ceramics


Article Preview

Chemical composition and uniaxial compressive stress are varied to observe their effect on the current-voltage behaviors of ZnO based ceramics. Chemical composition variation produces two kinds of ceramics showing ohmic and nonohmic current-voltage behaviors. The current at a fixed voltage is increased with the increase of the compressive stress for both ceramics. Ceramics with nonohmic behavior shows better reversible return of current-voltage curve when the applied compressive stress is removed from the ceramic than those with ohmic behavior do. We found out an appropriate chemical composition showing linear relation between current and stress at a fixed voltage as a potential application of the ceramic material to pressure sensor.
