Patent ID: 8785914

Claim:
An electronic device comprising: a first electrode and a second electrode spaced apart from each other; a plurality of piezoelectric nanowires disposed on the first electrode; and a piezoelectric organic material layer disposed between the second electrode and the plurality of piezoelectric nanowires, wherein the piezoelectric organic material layer comprises a composite material including an organic material, the organic material including one of polyvinylidene fluoride (“PVDF”), poly(3-hexylthiophene) (P3HT), polyaniline, polypyrrole, poly(p-phenylene vinylene) (“PPV”), polyvinylene, polyacetylene, polythiophene, derivatives thereof, and combinations thereof, wherein the piezoelectric nanowires comprise an n-type semiconductor, and the piezoelectric organic material layer comprises a p-type organic semiconductor generating electron-hole excitons by adsorbing light.
