Abstract
The present study reveals that ZrO2 MOS capacitor has been fabricated by RF sputtering technique. The maximum refractive index has been found to be 2.29 at 400 °C. From capacitance-voltage graph, it has been observed that the memory window and accumulation capacitance has been found to be maximum at 400 °C. The maximum memory window and accumulation capacitance has been found to be 0.50 V and 7.00 ×10−11 F, respectively. The flat band voltage shifts toward positive side at all temperatures. From current-voltage curve, it has been observed that the leakage current is found to be low at 400 °C and it is order of 10 − 7A at +20 V.
