Remote imprinting of moiré excitons via twisted hBN

/in /by

New work in Nano Letters led by Minhyun Cho in collaboration with the groups of Young Duck Kim, Gabriele Grosso, Jiel Jung and Jim Hone demonstrate the remote imprinting of moiré excitons using the ferroelectric domains in twisted hBN.

Direct writing of polariton condensate lattices at room T

/in /by

The work appears in Nano Letters – led by Dr. Ravindra Kumar Yadav

Here we report the realization of a room temperature polariton condensate lattice using a direct-write approach. Polariton condensation is achieved in a microcavity embedded with an organic dye (rhodamine) in a small-molecule ionic isolation lattice (SMILES). The microcavity is patterned using focused ion beam etching to realize arbitrary lattice geometries, including defect sites on demand.

Plug and play room temperature polariton condensates arrive!

We show polariton condensation in one of the most widely used dye – Rhodamine using the SMILES matrix.  The work led by Sitakant and Prathmesh in collaboration with the groups of Matthew Sfeir (CUNY ASRC), Amar Flood (Indiana) and Bo Laursen (Copenhagen) appeared in ACS Photonics
