Nanoscale Quantum Materials Department

Directors: Jie Shan & Kin Fai Mak

At the Department of Nanoscale Quantum Materials, our research focuses on synthesizing and studying two-dimensional (2D) van der Waals quantum materials and their heterostructures. We develop and explore these novel 2D systems, uncovering a fascinating range of phenomena and states of matter, such as unconventional superconductivity, strongly correlated excitonic insulators and topological states. Unlike classical forms of matter with their inherent physical properties, these novel 2D materials allow us to control specific properties or quantum phases by adjusting experimental parameters.

The assembly of these materials relies on precisely stacking atomically thin crystals into complex layered structures, often incorporating a rotational angle between individual layers that profoundly influences the electronic properties. Using advanced nanofabrication techniques and tools, we pattern these intricate stacks into nanostructures. Across a wide temperature range, from room temperature to just a few millikelvin near absolute zero, we probe their optical, electronic and magnetic properties and examine the internal degrees of freedom of electrons and emergent many body phases of matter.

Does this spark your curiosity? We are always seeking highly motivated students and scientist to join us on our scientific journey.
