This course covers basic surface physical chemistry relevant to applied science and engineering materials. Among the topics covered are: Surface structures of both crystalline and non-crystalline materials — relaxation, surface electronic structure — work function, band structure, interfacial phenomena, surface thermodynamics, the Gibbs construct, double layer theory, micellular structure, surface kinetics, catalysis, adsorption, adhesion and wetting. This is a companion course to JTC1135H, which covers analytical techniques for the study of surfaces and interfaces.
