(202) 478-8915

Shi Liu joins the Geophysical Laboratory from the University of Pennsylvania as a postdoctoral fellow. Shi is working with Ron Cohen on multi scale simulations of dynamical responses of ferroelectric domains, to fundamentally understand various structure-property relationships of ferroelectric domain walls and to discover, develop and demonstrate new material design principles. His research interests focus on materials exploration and design using both advanced quantum chemistry and large-scale molecular dynamics simulations.

Washington, DC—It would be difficult to overestimate the importance of silicon when it comes to computing, solar energy, and other technological applications. (Not to mention the fact that it makes up an awful lot of the Earth’s crust.) Yet there is still so much to learn about how to harness the capabilities of element number 14. The most-common form of silicon crystallizes in the same structure as diamond. But other forms can be created using different processing techniques. New work led by the Geophysical Laboratory's Tim Strobel and published in Physical Review Letters shows that one form of silicon, called Si-III (or sometimes BC8), which is synthesized using a high-pressure process, is what’s called a narrow band gap semiconductor.
The Geophysical Laboratory's Postdoctoral Fellow Shi Liu was awarded the 2017 APS Metropolis Award in late October.  The purpose of the award is to recognize doctoral thesis research of outstanding quality and achievement in computational physics and to encourage effective written and oral presentation of research results.
