【 摘 要 】

One of the innovative technological directions for the high-temperature superconductors has been persued by fabricating the heteroepitaxial multilayer structures such as superconductor–semiconductor heterostructures. In the present investigation, metal/superconductor/semiconductor (Ag/Tl-2223/CdSe) hetero-nanostructures have successfully been fabricated using dc electrodeposition technique and were characterized by X-ray diffraction (XRD), full-width at half-maximum (FWHM) and scanning electron microscopy (SEM) studies. The measurement of junction capacitance as a function of biasing voltage was used for the estimation of junction built-in-potential (𝑉D) and to study the charge distribution in a heterojunction. The Mott–Schottky plots were measured for each junction in dark and under the photo-irradiation. The effect of laser irradiation on 𝐶-𝑉 characteristics of hetero-nanostructure has been studied.
