How are Electrical Fields Generated at the Nanoscale?
Electrical fields at the nanoscale can be generated using various techniques:
Electrodes: Nanoscale electrodes can create localized electrical fields. By applying a voltage difference between two electrodes, an electrical field is established. Dielectric Materials: Placing nanoscale objects in a dielectric medium and applying an external field can induce a localized electrical field within the material. Piezoelectric Materials: Some nanomaterials exhibit piezoelectric properties, generating electrical fields in response to mechanical stress.
