Chemisorption on Perfect Surfaces and Structural Defects.

Abstract

Chemisorption of nitrogen and hydrogen on densely packed planes of tungsten, molybdenum, iridium, and rhenium has been studied by probe-hole field emission microscopy. Adsorption on perfect planes, as well as on planes containing structural defects, has been investigated. The results can be interpreted by the promotion of chemisorption at structural defects on smooth surfaces. A model, which can account for our results as well as observations on macroscopic surfaces, is presented. (Author)
