제목 Electrical properties for ZnIn2S4 Single Crystal Thin Film grown by Hot Wall Epitaxy
초록 Single crystal ZnIn2S4 layers were grown on a thoroughly etched semi-insulating GaAs(100) substrate at 450 ℃ with the hot wall epitaxy (HWE) system by evaporating the polycrystal source of ZnIn2S4 at 610 ℃prepared from horizontal electric furnace. The crystalline structure of the single crystal thin films was investigated by the photoluminescence and double crystal X-ray diffraction (DCXD). The carrier density and mobility of single crystal ZnIn2S4 thin films measured with Hall effect by van der Pauw method are 8.51×1017 electron/cm-3, 291 cm2/v-s at 293K, respectively. The photocurrent and the absorption spectra of ZnIn2S4 /SI(Semi-Insulated) GaAs(100) are measured ranging from 293 K to 10K.
