Graphene Isotope Superlattices with Strongly Diminished Thermal Conductivity for Thermoelectric Applications

Graphene has a high intrinsic thermal conductivity and a high electron mobility. The thermal conductivity of graphene can be significantly reduced when different carbon isotopes are mixed, which can enhance the performance of thermoelectric devices. Here we synthesize isotopic 12C/13C random mixes and isotope superlattices (SLs) with periods...

The interaction of light with WS2 nanostructures

In this thesis we describe three results of the interaction between WS2 and light: photoluminescence, the formation of exciton-polaritons and Raman scattering. The chirality of the photoluminescence interaction between WS2 and light opens the way for applictions in nanophotonics and specifically valleytronics, the field of interacting with and...
