摘要

Capacitance-voltage and current_voltage characteristics of Au-type Si (n-Si) and Au/poly(3,4-ethyl'enedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT:PSS)-Si Schottky diodes were investigated in this study. The interfacial phenomenon was explained in terms of the generation of an interfacial dipole subsequently affecting the electron-injection barrier. The authors found that inserting a PEDOT : PSS layer at the Au-Si interface may result in the formation of an interfacial dipole, increase the upward band bending in Si near the interface and reduce the reverse-bias leakage current. In this study, higher quality Schottky junctions were formed on n-Si using a simple technique of spin-coating PEDOT : PSS as the metal electrode.
