Abstract
Optical and electric properties of superthin niobium films (d=0.15-2.7 nm) deposited on alpha-quartz using radio-frequency sputtering have b een studied at room temperature and at low temperature. A periodic thi ckness dependence of the metal film's optical and DC conductivity was found. The period of such oscillations is of the order of the electron Fermi wavelength in Nb. Thus they are proposed to be due to quantum s ize effects in the metal film.
