Abstract
Transport properties of very thin (2.5 monolayer) films of Ag epitaxially grown on clean Ge (001) substrates are reported. The films consist of a monolayer coverage plus isolated three dimensional islands. Below ∼70°K the conductivity is dominated by the metal film and displays the temperature and electric and magnetic field dependences characteristic of metallic weak localization in two dimensions. Below ∼2°K the resistance drops rapidly in a manner resembling an incomplete superconducting transition. The resistance is restored by application of a magnetic field of ∼20 KGauss at 0.6°K.
