Event Description:

Two-dimensional (2D) materials are exciting new additions to photonics, enabling new paths in research and potentially leading to innovative practical components. Van der Waals heterostructures are constructed of 2D materials such as transition metal dichalcogenides (TMDs) and hexagonal boron nitride. The special properties of these materials enable the exploration of new physics and quantum-optical effects. We will explain how new devices built by stacking monolayers of MoSe2 and WSe2 are used to explore the nature of optical generated excitons. The photoluminescence energy of these excitons can be tuned by applying electric fields and we are able to observe diffusion across samples as well as control their energy, movement, and density. The results pave the way for new optoelectronic devices and are a step towards exploring Bose-Einstein condensates at high temperatures in a solid state platform. We will also show new developments in spectroscopic equipment and scientific cameras that facilitate this research with unprecedented sensitivity for detection in the near IR wavelength range.
