Bias voltage is fundamental in nanotechnology for several reasons:
Device Operation: It enables the functioning of nanoscale devices like transistors and sensors by controlling the flow of electrons. Material Characterization: Bias voltage is used in techniques such as Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM) to probe the properties of nanomaterials. Energy Band Manipulation: It can alter the energy band structure of materials at the nanoscale, affecting their electronic and optical properties.
