The authors report here the experimental evidence of semiconductor-superconductor transitions in relatively thick Nb/Al structures. The temperature dependence of resistivity {rho}(T) shows a sharp superconducting transition followed by either a normal metallic behavior in low-resistivity samples, or a semiconducting behavior when the sample resistivity at 10 K is above 100 {mu}{Omega} cm. The authors discuss here the fabrication conditions and the electron localization regime associated with the measured {rho}(T) dependence.
