چكيده فارسي :
A composition of ZnO-polymer tiny particles was pressed at a temperature of 120 °C and a pressure of 60 MPa and its current-voltage characteristic was studied. The result shows that the prepared disk has varistor behavior and can therefore be used to protect circuits from low overvoltage transients. Temperature dependence of current-voltage characteristic and the potential barrier of the sample were investigated in the temperature range of 11-50 °C. It has been found that increase in temperature results in lower breakdown voltage, higher nonlinear coefficient and higher potential barrier high, as well.
