Research
Our research interests focus on the
electronic properties of two-dimensional (2D) van
der Waals materials. Individual atomic planes of
the bulk crystal can be exfoliated, with the
extracted monolayers often having surprising new
properties compared to the bulk material. Our
current efforts are focused on three main areas:
Topological Electronic States
Many 2D materials exhibit electronic
states with topological properties. These
properties can be intrinsic or emerge in
conjunction with superconductivity. These states
show promise towards topological quantum computing
and solid-state manipulation of quantum
information.
Proximity Coupling
An advantage of 2D materials is that the
individual layers can be readily stacked to make
atomically precise heterostructures. Such
heterostructures can be tailored to create
synthetic materials that do not appear in nature
and exhibit novel phenomena.
Twistronics
The properties of heterostructures can also be
tailored by the interlayer twist angle, giving
even more degrees of freedom with which to tune
material properties. For example the spatial
interference between the twisted lattices creates
a long-wavelength superlattice. This superlattice
can profoundly alter the behavior of the
materials, producing a plethora of interacting
many-body states and correlated phases that
exhibit such behavior as superconductivity or
magnetism.
