| 中文摘要 | The Zn0.32Co0.68O1-v/Pb hybrid junctions were prepared, where the concentrated magnetic semiconductor Zn0.32Co0.68O1-v is in the region of variable range hopping transport instead of the ballistic or diffusive transport. The high differential conductance peak at gap voltage and two above-gap peaks were observed below the superconducting critical temperature. Moreover, both the zero bias conductance peak and the finite bias conductance peak were observed below the gap voltage. All these differential conductance peaks systematically evolve and finally disappear as the temperature or the magnetic field increases. These transport phenomena were explained by phase coherent Andreev reflection in the presence of strong disorder, magnetic impurity scattering, and spin polarization. (C) 2013 Elsevier B.V.
