Material systems, devices, and circuits, based on the manipulation of individual charges, spins, and photons in solid-state platforms are key for revolutionary quantum technologies. The burgeoning field of quantum two-dimensional (2D) materials presents an emerging opportunity for breakthroughs in the development of next-generation quantum technologies while also pushing the boundaries of fundamental understanding in condensed matter. Our laboratory aims to create quantum functionality in 2D systems by combining fabrication and assembly techniques of 2D layers with atomically precise scanning probe microscopy.
In this talk, I will focus on three research directions. Firstly, I will discuss scanning tunnelling microscopy and spectroscopy experiments aimed at elucidating the nature of atomic-scale defects in 2D materials and at creating novel moiré structures by twisting 2D layers. Secondly, I will present our progress in realizing quantum-confined devices in 2D semiconductors. Lastly, I will show how we leverage our expertise in probing and engineering electronic states at surfaces of 2D materials to further the development of graphene-based gas sensors.
