Phaedon Avouris, who serves as Manager at the Nanometer Scale Science and Technology division of the T.J. Watson Research Center of IBM, will deliver a presentation titled ‘Graphene-based Electronics and Optoelectronics’ at the AVS 58th International Symposium & Exhibition in Nashville, Tennessee.
In the presentation, Avouris will discuss about his new experimental findings based on the application of graphene in photonics and electronics. He will also explain the necessity to convert these innovations into commercial products.
Avouris stated that graphene’s intrinsic properties can be radically affected by the interference of graphene with the substrate on which it is placed, other substances in a device, or the ambient surroundings. His area of focus is to understand graphene’s intrinsic properties under actual technology conditions and use this data to design, produce and examine electronic and optoelectronic circuits and devices based on graphene, he said.
Graphene cannot be used for designing digital switches, as band gap is absent in the material, Avouris said. However, graphene’s superior electrical properties, including its superior electron mobility along with current modulation, enable it a suitable material for high-frequency or ultra-fast analog electronics utilized in imaging, security systems, radar, wireless communications and more, he added.
Avouris further said that he has illustrated high-frequency graphene transistors over 200 GHz, basic electronic circuits, including frequency mixers, and ultra-fast photodetectors to sense optical data channels. In the coming years, scientists will pay attention to enhance synthetic graphene quality and analyze its properties under technology conditions, he concluded.
