[18p-133-10] Characterization of the electronic structure at CdS/Cu2ZnGeSe4 heterointerface
Keywords:Band offset, Kesterite, UPS/IPES
We will report the electronic structure at the interface between CdS and Cu2ZnGeSe4 (CZGSe), which relate with the solar cell performances, by using ultraviolet photoemission-, inversed photoemission-, X-ray photoemission spectroscopy (UPS, IPES, and XPS).
