Abstract

The low-voltage ZnO varistor fabricated by a new method with three-composition seed grain are studied. The knee voltage about 5V$\_$0.5[A/$\textrm{cm}^2$]/ for sample #7 among the various samples are observed, and activation energy in the obmic region and trap level in the double sohottky region for each samples are 0.359∼0.450eV and 0.553∼0.620eV, respectively. It is concluded that the change of knee voltage may be caused by trap level in double sohottky region rather than activation energy in the ohmic region.
