摘要
A hybrid p-n junction was fabricated by using chemically synthesized cadmium sulfide (CdS) nanoparticles and spun films of poly (9-vinayl carbazole) (PVK). The junction appeared to be nearly ideal from the current-voltage measurements. The analysis of capacitance-voltage characteristics produced a value of nearly 1V for the zero bias built-in barrier of the CdS/PVK junction. The high photoresponsivity in the order of 1.16AW(-1) at -2V may be attributed to dissociation of loosely bound excitons at the CdS/PVK interface.
