Stacking and Twisting 2D Materials for Quantum Nano-Optoelectronics: Fundamentals and Applications
Hosted By: Quantum Optical Science and Technology Technical Group
14 September 2021 8:00 - 9:00
Eastern Time (US & Canada) (UTC -05:00)Two-dimensional (2D) materials have emerged as a novel toolbox to build new materials and devices atom-by-atom. In this webinar jointly hosted by the Quantum Optical Science and Technology Technical Group and the Optical Material Studies Technical Group, Frank Koppens from ICFO – The Institute of Photonic Sciences will present new ways to control light and electrons at the atomic scale by stacking and twisting 2D materials.
In particular, Prof. Koppens show nano-optoelectronic devices for applications as well as the novel nanophotonic properties. The limits of quantum light-matter interactions have been challenged by approaching optical field confinement down to the length-scale of single atoms. Prof. Koppens will also present nano-optoelectronic studies on twisted bilayer graphene using scanning near-field optical microscopy. Twisted bilayer graphene near the magic angle (MABG) exhibit strongly correlated phases have been observed, including superconductivity and the Mott-like insulating state. Several device applications, such as detectors for infrared and THz light, will also be discussed.
