Resonant Activation of Resistive Switching in ZrO2(Y) Based Memristors
We report on a comparative study of resistive switching in the memristors based on ZrO 2 (Y) films and on ZrO 2 (Y)/Ta 2 O 5 bilayer stacks by triangle voltage pulses with superimposed high-frequency sinusoidal signal. The dependencies of the current difference in the low resistance state and in the...
