In-Situ Microscopy and Spectroscopy of Advanced Materials


Tuesday, January 28, 2014, 01:30pm - 02:30pm

Experiments capable of interrogating materials with high spatial, temporal, chemical, and energy resolution in complex environments promise to play a central role in accelerating the discovery of new materials synthesis and processing routes, and in fostering a fundamental understanding of the physics of advanced functional materials. Here, I discuss our recent development of surface sensitive in-situ and in-operando methods applied to two-dimensional (2D) materials and materials for sustainable energy conversion.

2D crystals represent a new class of multifunctional materials that show promise for a wide range of applications. Real-time surface microscopy and associated analytical methods provide unique insight into the synthesis, processing and properties of atomically thin materials such as graphene, hexagonal boron nitride, as well as engineered nanoscale 2D heterostructures. Novel in-operando probes are uniquely positioned to shed light on the interaction of materials for sustainable and energy-efficient chemical processes with their environment, thereby providing a basis for the rational design of systems that function optimally under industrially relevant conditions.

Our combined results illustrate the power of in-situ and in-operando methods for achieving and probing novel functionalities in advanced materials.
