Two-dimensional (2D) materials have emerged as a novel toolbox to build new materials and devices atom-by-atom. By stacking and twisting 2D materials, new ways to control light and electrons at the atomic scale. In particular, we will 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.

We 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.
