Nanomaterials for optoelectronic devices

Through molecular design and synthesis, we have synthesized many nanoparticles and fabricated into optoelectronic devices. Au-C₆₀ arrays were deposited on the top of pairs of gold electron to single electron transistors. Silica nanoparticles were used to create nano-structure on silicon and fabricated into infared light emitting diode (LED). CdS and CdSe nanoparticles have been fabricated into visible light LEDs. CdSe nanoparticles can be infiltrated into self-assembled photonic crystal to modulate light emission and light reflection. CdS nanoparticles were hybrid with MEH-PPV to fabricate photovoltaic devices.
