Electrical and interface characteristics of nanocrystalline n-Zn0.5Cd0.5S/p-Cu2S heterojunction structure prepared by dip coating

► We develop a dip coating to prepare nanocrystalline n-Zn0.5Cd0.5S/p-Cu2S heterojunction. ► The energy distribution profile of Nss was extracted from I-V measurements. ► Temperature dependence of both ideality factor and barrier height was studied.
