The ability to transport extracted carriers from the development of NQDs (nanocrystal quantum dots) based optoelectronic sensors have drawn considerable attention due to NQDs’ unique optical properties. Coupling of NQDs to 1-D nanostructures such as SWNTs (single-walled carbon nanotubes) is expected to produce a composite material which facilitated selective wave length absorption, charge transfer to 1-D nanostructures, and efficient electron transport. In this research, we fabricated the optoelectric device based on Cadmium Selenide (CdSe) nanocrystal quantum dots (NQDs)/single-walled carbon nanotubes (SWNTs) heterostructure using dieletrophoretic force. The efficient charge transfer phenomena from CdSe to SWNT make CdSe-Pyridine (py)-SWNT unique heterostructures for novel optoelectric device.
