2011 Van Vlack Lecture Series - Structure of Liquids and the Crystal-Liquid Interface


Frans A. Spaepen, Harvard School of Engineering and Applied Sciences

Identifying the principle that underlies the structure of even the simplest liquids is an enduring scientific challenge. Starting with the basic facts about liquids, this talk will critically review the structural models that have been proposed over the decades. In the picture that emerges, the liquid is a phase in its own right (not a defective crystal, nor simply a dense gas) with a polytetrahedral structure. This structural principle can be used to understand the interface between crystals and liquids and its role as the barrier for crystal nucleation from the melt.

 

The Van Vlack Lecture Series was established in honor of L. H. Van Vlack, to provide a distinguished lecture series from the outstanding leaders in the field of Materials Science and Engineering
