for a low operating voltage of −5 V, along with excellent electromechanical stability. Furthermore, these devices showed excellent environmental stability with almost unchanged electrical characteristics for 26 weeks. Moreover, devices showed high cyclic stability with stable ON/ OFF switching characterized up to 500 cycles.
