CFN Research Activities

DFT-based methods and many-body perturbation theory form the core tool-box we use to understand the properties of materials from the atomic scale up. For example, we seek to understand the structure motifs that emerge at semiconductor aqueous interfaces in equilibrium, connect those interface structures to the energy level alignment between the semiconductor band edges and redox levels in the electrolyte and the implications of the structure motifs for electrocatalytic activity. Other exemplary nanomaterials systems we consider include electron transport through nanoscale junctions, electronic and optical properties of atomically thin 2D materials, and the interplay between phase formation and electrochemical characteristics of materials for energy storage applications.
