Enabling design of materials by understanding unit mechanisms of atomic structure evolution

 
Materials with complex, often non-crystalline atomic structures hold great promise as constituents for nano-composites that survive in extreme conditions of energetic ion bombardment, high mechanical loads, and fluctuating temperatures. To realize the full technological potential of such materials, fundamental challenges to our understanding of the unit processes governing their atomic-scale behavior must be solved. I will illustrate how atomistic simulations can meet these challenges by demonstrating that understanding point defect behavior at interfaces between incommensurate crystals provides strategies for informed design of radiation resistant materials for use in next generation nuclear reactors. I conclude by discussing new directions in materials research where recognizing the unit processes of atomic structure evolution is crucial for developing scientific understanding and technological applicability of non-crystalline materials.
