Представлен статистическо-механический подход к изучению поверхностной диффузии с помощью модели газовой решётки. Обсуждаются общие формулы для функции покрытия химических и скачковых диффузионных коэффициентов при низких температурах и в локальном равновесном пределе. Также обсуждается использование специфической двухмерной модели.

A statistical mechanical approach to study surface diffusion by lattice-gas models is presented. General formulas for the coverage dependences of chemical and jump diffusion coefficients are discussed at low temperatures and in the local equilibrium limit. An application to a specific two-dimensional model is considered.
