- Abstract
- We experimentally investigated a DC voltage bias effect on laser-induced switching bistability observed in vanadium dioxide (VO 2) thin film through the illumination of the film with a laser at ~1.55 μm. The bias effect on the bistable switching was examined in a circuit composed of a VO 2-based device, DC voltage source, and resistor. At different bias values, static and transient responses of the circuit current were observed by varying illumination power. Specific bias voltages could change the bistable switching into irreversible unidirectional switching, thereby requiring the proper selection of the bias voltage for the stable operation of the bistable switching. © 2012 The Japan Society of Applied Physics.
