Capacitance–voltage and current–voltage characteristics of Au Schottky contact on n-type Si with a conducting polymer

Capacitance-voltage and current-voltage characteristics of Au/n-type Si (n-Si) and Au/poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT:PSS)/n-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/n-Si interface may...
