Project A01 focuses on creating and manipulating collective molecular states formed by organic dye molecules assembled into monolayers on 2D materials such as graphene, hBN, and TMDs. By varying the molecules and 2D substrates, it engineers’ lattices with different symmetries and coupling strengths. This leads to emergent effects like collective molecular excitons and potential superradiant states with unique optical properties.

Experimental methods: physical vapor deposition (PVD), atomic force microscopy (AFM), and fluorescence, absorption and Raman spectroscopy
