Surface Energy and Crystal Structures

This lecture covers various aspects related to surface energy and crystal structures, including methods to compute surface energy, the relationship between surface energy and crystal shape, surface stress, ideal vs realistic crystal surfaces, and models like Terrace-Ledge-Kink. It also delves into crystallography concepts, interfacial energy, Young's theorem, nucleation, micelles, Debye Length, pH effects, Gibbs and Langmuir isotherms, and grain boundaries. The instructor provides detailed explanations and examples to help understand these fundamental concepts.
