Fabrication and characterization of p-poly(9, 9-diethyl fluorene)/ n-ZnO nanorods hybrid heterojunction

The p-poly(9,9-diethylfluorene) (PDEF)/n-ZnO nanorods(ZNR) heterojunctions were prepared by spin-coating p-type conductive organic polymer on as-prepared n-ZNRs which were fabricated by hydrothermal solution method. This hybrid nanorod p-n heterojunction shows good rectifying behavior with turn-on v...

Description
Summary:The p-poly(9,9-diethylfluorene) (PDEF)/n-ZnO nanorods(ZNR) heterojunctions were prepared by spin-coating p-type conductive organic polymer on as-prepared n-ZNRs which were fabricated by hydrothermal solution method. This hybrid nanorod p-n heterojunction shows good rectifying behavior with turn-on voltage of about 0.5 V at room temperature. A rectification ratio of 39.8 was realized. The hybrid nanorod heterojunction shows good responsivity toward visible light, and the current-voltage characteristics have been analyzed with and without visible light. These results present potential applications in the future nano-electronic and photonic devices based on organic and inorganic p-n heterojunction arrays.
