What is it about?

Layered heterostructures allow for the creation of new phenomena via proximity effects. We have discovered the first evidence for the modification of exciton physics in 2D semiconductors by a proximitized charge density wave. This result shows a new method for engineering the optical properties of 2D materials by interfacing with strongly correlated materials.

Why is it important?

This work is important as it is the first instance of using a charge density wave to alter exciton physics in 2D materials. It points the way towards manipulating optical physics by tuning the charge density waves.


It was a pleasure to work on this paper, a labor of love during the pandemic!
