W04 - Energy and charge transfer in organic/inorganic van der Waals heterostructures
Project description

In project W04, we will study charge and energy transfer processes in organic/inorganic heterostructures consisting of molecular layers and semiconducting two-dimensional transition-metal dichalcogenides. We will fabricate these structures using deterministic transfer and study their electronic properties and interlayer coupling via time- and spatially resolved photoluminescence at variable temperature. In parallel, we will perform atomistic simulations of our hybrid systems based on density functional theory employing system-specific optimization of screened range-separated functionals. Charge separation and nonradiative transitions will be studied using nonadiabatic molecular dynamics simulations via semiclassical surface hopping.
