Surfaces

Über

This primer provides an introduction to the subject of surfaces at the level of undergraduates and first year postgraduates. There are four chapters, the first concerns basic thermodynamic material used to understand the properties of surfaces including; surface tension, Gibbs absorption, surface pressure and surface phase equilibria, surfactants and micelles, wetting, detergency, and contact angle. The second chapter concentrates on gas absorption at solid surfaces and covers topics including absorption, Langmuir isotherms, heats of absorption, BET isotherms, physisorbtion, chemisorbtion, precursor absorption kinetics, well-defined surfaces, UHV, surface sensitivity and selectivity, surface diffusion and electrons interacting with matter. Chapter three then outlines the physico-chemical principles of XPS, AES, LEED, STM, AFM, work function measurements, UPS, TPD, molecular beams, HREELS and PAIRS and the types of fundamental surface information each of these techniques provides. The final chapter contains a series of worked examples and problems, bringing together the various strands developed in Chapters 1-3 in order to elucidate surface phenomena. The book is unique in its mix of 'Classical' and 'Modern' surface science and should be relevant to physicists, chemists and material scientists.
