摘要：

We study how the proximity effect in a ferromagnetic semiconductor (FS)/superconductor (SC) junction is manipulated by the mismatches of the band and mass between the FS and SC, as well as the strength of potential scattering at the interface. It is demonstrated that they have different influences on the superconducting order parameter and density of states in the FS and SC induced by the proximity effect, particularly on the features of gapless superconductivity and transition from the "0 state" to the " pi state," which is different from those in ferromagnet/SC junctions.
