Four Lectures on the Physics of Crystal Growth

Joachim Krug
Four Lectures on the Physics of Crystal Growth
Several aspects of the theory of epitaxial crystal growth from atomic or molecular beams are developed from the perspective of statistical physics. Lectures are devoted to the rate equation theory of two-dimensional nucleation and its limitations; the growth of multilayer...
