Quasiparticle dynamics and optical properties of 2D materials
The goal of my group‘s research is to prepare and chemically functionalize
layered materials and then to characterize them in-situ using a novel
combination of photoelectron and optical spectroscopies. This approach
provides a solution to the intense research efforts in trying to engineer,
probe and unravel many-body physics and the superconducting coupling
mechanism in layered solids. Regarding the materials under investigation,
I will show results from the growing family of 2D materials such as
graphene, hexagonal boron nitride, transition metal dichalcogenides and
phosphorene. Chemical functionalization using dopants allows for an unprecedented
control over their physical properties. The proposed material
systems provide a new arena to explore diverse condensed matter
phenomena such as electron correlation, electron-phonon coupling and
superconductivity.
