Carbon nanotubes and graphene-based semiconducting materials exhibit exceptional properties and behaviors and unique physical phenomena that make them highly attractive for next-generation optoelectronic and photonic devices. Overall, in this project, we are building on our groups unique abilities for creating precision-controlled carbon semiconductors and exploiting their exceptional characteristics to engineer next-generation carbon-based optoelectronic and photonic devices with superior performance and capabilities. These devices include carbon nanotube-based photovoltaic, photodetector, and light emitting devices, which build on our capabilities for creating highly monodisperse electronic-type-controlled and bandgap-controlled semiconducting nanotubes 1-3, as well as preliminary demonstrations of carbon nanotube donoracceptor heterojunction diode devices in which the nanotubes are the light absorbers3-7. These devices also include semiconducting graphene optoelectronic and photonic devices, which build on our capabilities for creating structure-controlled nanopatterned graphene with tunable, semiconducting behavior and with refined edge structures 8-11. Overall, work focuses on the study of materials optoelectronic and photophysical properties and new fundamental concepts in devices that exploit the exceptional properties of these nanocarbon materials.
