Description
Optical and electric properties of superthin niobium films (d=0.15-2.7 nm) deposited on α-quartz using radio-frequency sputtering have been studied at room temperature and at low temperature. A periodic thickness 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 size effects in the metal film. (orig.)
