Condensed Matter Seminar

In this talk I will provide a brief overview of two recent accomplishments in my group toward achieving quantum emitters capable of operating in telecommunication wavelength and generating circularly polarized single photons without the need of external magnetic field and spin polarized injection of carriers/excitons.  

 

Graphene is not the only two-dimensional material with far-reaching significance. It falls into the category of van der Waals (vdW) materials which can be exfoliated down to atomically thin monolayers. Thousands of them have been created and can be further assembled into designer heterostructures like quantum Lego. Stackings can induce moiré patterns, sparking major efforts in the studies of resultant new electronic phenomena in vdW heterostructures.
