Effect of Surface Charge on the Superconductivity of Vanadium Films

  • W. Felsch


Electrostatic charging affords a direct method of changing the number of electrons at the surface of a metal film The sample serves as one plate of a capacitor across Which a voltage is applied. Charging occurring at the surface of a superconducting film with thickness smaller than the coherence length can be expected to affect the superconducting transition temperature of the entire sample. This “superconducting field effect” has previously been investigated for a considerable number of metals (see, e.g., Ref. 1).
