2nd Funding Period
Local-Scale Optoelectronics of Synthetic 2D Materials
The project aims at quantifying the two relevant parameters relevant for optoelectronic applications of low-dimensional 2DMs at the nanometer length scale, that is the anisotropic tensors of both the electronic conductivity δ(ω) and the dielectric permittivity ε(ω) (also known as the “optical” conductivity).
1st Funding Period
Local-Scale Fingerprinting of 2D Hybrid Materials
The project will focus on the in-situ vibrational and electronic characterization of 2DMs down to the 1-nm length scale. When applying scanning probe methods, i.e. Kelvin probe force microscopy (KPFM) and coherent anti-Stokes Raman scattering (nano-CARS) at the nanometre-length scale, it will be able to quantify the local electric field environment and local bond strengths, that then allows differentiation between defects and dopants from intact stacked 2DMs by their physico-chemical fingerprints. Such methods allow specifying the surface reactivity and chemical functionality at different edge and basal-plane sites. A time-resolved variant of KPFM constituting a novel approach for investigating electronic transport in 2DMs will be developed.
