Research Description

The overarching goal of my research is the creation and characterization of low-dimensional electron systems and their optimization for inducing emergent phenomena arising from electronic correlations. My group employs transport measurements at low temperatures and high magnetic fields, as well as scanning tunneling microscopy and spectroscopy, to elucidate the electronic properties of low-dimensional materials and their response to external perturbations such as stress, charge impurities, boundaries, and substrate materials.

We are particularly interested in atomically thin (two-dimensional) crystals such as graphene and transition metal dichalcogenides, as well as hybrid systems obtained by stacking layers of these two-dimensional crystals. Interactions between stacked layers can radically change their properties, leading to essentially new materials in terms of the electronic structure. For instance, we were the first to demonstrate that it is possible to control the electronic properties of a two-dimensional material without changing its chemical composition by superposing two layers of graphene with a twist between their crystal orientations. The emergence of special electronic energy bands (flat bands) in these twisted layers has subsequently led to important discoveries including superconductivity and other correlated electronic states. Our group currently actively investigates these emergent phenomena in twisted layers. In addition, we are exploring new pathways for engineering flat bands in two-dimensional materials, for example, using buckling transformations and substrate patterning.
