 Election Citation
Avouris' experimental and conceptual efforts have done more to advance nanoscience than any other currently active experimentalist. His imagination, exacting experiments, clear explanations, and the combination of fundamental and applied advances from his laboratory have enabled understanding and widespread applications of molecular, semiconductor, nanotube, and graphene-based systems and devices.
 Research Interests
Phaedon Avouris' research interests involve primarily the understanding of the relation between electronic structure and the electrical and photonic properties of carbon nanostructures such as carbon nanotubes and graphene and their possible use in novel electronic and photonics technologies. The work involves experiments and theoretical modeling, as well as the fabrication and study of model devices. This work led to the first carbon nanotube field effect transistors, logic gates, integrated electronic circuits and photon detectors. Similar results were achieved based on graphene, including the development of GHz high frequency transistors, integrated circuits, infrared detectors and plasmonic devices. Earlier work focused on the behavior of molecules adsorbed on surfaces. Avouris used scanning tunneling microscopy and spectroscopy (STM/S) to image on the atomic scale how chemical reactions take place at metal and semiconductor surfaces and study the factors that determine the reactivity of surface sites. He also used the STM to manipulate individual atoms and molecules at surfaces.
