Abstract:

Fabrication of nanostructures with tight control of chemical composition, size, and crystal structure over wafer-scale distances is a major bottleneck for accelerated materials discovery and screening. New breakthroughs in nanomanufacturing require an improved understanding of confinement effects that dominate during fabrication. In this talk, I will detail how enhanced diffusivity and creep at the nanoscale can be exploited to further develop a new nanomanufacturing technique, thermomechanical nanomolding (TMNM). I will show how TMNM can enable controlled tuning of grain size/crystallographic orientation in 1D/2D nanostructures over wafer-scale distances and stabilization of unexplored metastable compounds.
