The effect of bias voltage on nanoscale devices is profound. For example:
Transistors: In nanoscale transistors, the gate bias voltage controls the conductivity of the channel, switching the device between on and off states. Sensors: In chemical and biological nanosensors, bias voltage can modulate the sensitivity and selectivity of the device. Memory Devices: In nanoelectromechanical systems (NEMS), bias voltage is used to store and retrieve information by changing the state of the system.
