Probing reactive deposition and surface dynamics using in situ, real-time emission microscopy

Abstract

Emission microscopy images of surface processes during chemical vapor deposition and catalytic reactions show a number of dynamic reaction phenomena that illustrate problems suitable for observation with the emission microscope: nucleation and growth of adsorbed layers, adsorbate controlled diffusion from the bulk, pattern formation, melting and evaporation. A qualitative examination of deposit morphology is made and is compared to the formation of Liesegang rings.
