A Study on the Switching Characteristics of PLT(10) Thin Films

초록

Switching characteristics of the PLT(10) thin film have been studied with varying the top electrode areas, input pulse voltages and load resistances. As the external input pulse voltage increases from 2 to 5 V, switching time decreases from 0.49 to 0.12μs. The activation energy (Ea) is obtained as 209 kV/cm from the relation between the switching time and applied pulse voltage. The switched charge densities at 5 V obtained from the hysteresis loop and the polarization switching are 11.69 and 13.02μC/cm2, respectively, which agree relatively well with each other. As the top electrode area increases from 3.14×10-4 to 5.03×10-3 cm2 with the load resistance of 50Ω, switching time increases from 0.12 to 1.88μs. As the load resistance increases from 50Ω to 3.3 kΩ with the top electrode area of 3.14×10-4 cm2, switching time also increases from 0.12 to 9.7μs.
