A Brief Tutorial on Interfaces

Instructors: Dominique Chatain & Wayne D. Kaplan

Hosted:  January 22, 2014 from 7:45 to 9:45 p.m.


The goal of this tutorial is to introduce the majority of the topics which will be discussed during the Basic Science Division Symposium on Interfaces, held during EMA. The specific issues for discussion have been selected based on titles of the invited talks, and the particular interest of the instructors. The issues for discussion include:


  1. Equilibrium Segregation/Adsorption Thermodynamics The correlation of interface chemical and structural excess with energy. What are “monolayers” and what is the best way to measure/describe them?
  2. Macroscopic and Microscopic Degrees of Freedom at Interfaces Five macroscopic degrees of freedom. Microscopic degrees of freedom and their connection to adsorption. Epitaxy, heteroepitaxy, and general orientation relationships. Coherent versus incoherent interfaces, and the issue of reconstruction.
  3. Interface Complexions and Complexion Transitions Cahn’s wetting transition. Interface adsorption transitions.
