摘要: Multilayer Nb0.53Ti0.47/Ge superlattices with varying Nb0.53Ti0.47 and Ge layer thickness were sputter deposited on sapphire substrates at 200°C. The physical properties of these depend the which is in turn related to degree disorder metal layer. spectrum samples can be subdivided roughly into three regions according their different transport properties—a superconducting region, a weak localization region strong region. sheet resistance, R□ films range 300ω magnetoresistance anisotropic for both weakly strongly localized perpendicular always larger than parallel values. transition consistent theoretically predicted mobility edge near R□≂ħ/0.12e2≅30kω.
