Dr. Epstein is an Assistant Professor at the Department of Physical Electronics, School of Electrical Engineering. He holds a B.Sc and a M.Sc (Magna Cum Laude) in physics, and a PhD in physical electronics from Tel Aviv University, Israel. After a time period spent as a postdoctoral fellow at ICFO - The institute of photonic sciences, Barcelona, Spain, at the group of Prof. Frank Koppens, he joined the Department of Physical Electronics at TAU as faculty, establishing the Light-2D Matter-Interaction research group (L2DMI).
The interaction between light and 2D materials spans from the ultra-violet spectrum all the way to microwaves. It involves a variety of different physical systems and quasi-particles, such as plasmons, excitons and phonons, which interact strongly with light. These light-matter interactions, can also occur in the form of polaritons, i.e. a quasi-particle that is composed from a photon and an excited state of matter (electron, phonon, exciton, etc).
In the group we study the interaction between light and 2D materials, the physical and optical phenomena they inhabit, and their polaritonic nature. We utilize several experimental techniques to perform room-temperature and low-temperature electro-optical spectroscopy, from the visible to the far-infrared spectrum. We develop robust optical methods specifically adapted to 2D material and their atomic dimensions. Doing so allows us to study the extraordinary properties of 2D materials, to push nanophotonics into the atomic scale, and to build atomic-scale electronic and opto-electronic devices.
