Rational-design of Meta-stability and Evolution of Advanced Materials

In our lab we target meta-stable materials that often include high degrees of (static or dynamic) disorder, such as glasses, high-entropy alloys, soft-semiconductors (e.g., halide perovskites), and phase-change materials. While these materials are candidates for neuromorphic computation applications, and energy recycling, harvesting and storage applications, their high degree of disorder require non-traditional approaches to create links between their structure and functionality. Often, these systems are dynamically changing during their functionalization and exist out of a thermodynamic equilibrium. Therefore, to understand them and rationally guide their development, one must follow and control their structural evolution. 

We develop experimental and analytical data-driven tools to learn about the strucutral evolution from the earliest states of disorder towards ordering, try to understand what (de)stabilize meta-stable materials, and how one can control their evolution.

What do we do? 

• We Learn about regenerative materials to gain better understanding and control over their chemical stability and functionality.
• We develop data-driven experimental approaches, assisted by AI tools, for an in-situ/operando strucutral evolution investigation.
• We study the complexity of meta-stable states by disentangling their structural and chemical nature.
• We develop active control approaches of functionalizing meta-stable and regenerative materials
