Hydrogen-induced reconstruction of the Mo(100) surface: Infrared, LEED and desorption kinetic studies.

The occurrence of adsorbate-induced substrate reconstruction provides a striking demonstration of collective interactions in surface phenomena. Hydrogen on Mo(100) appears to be the best model system to study these interactions because it exhibits a remarkable number of different reconstructed phases over small coverage and temperature ranges. Yet, regions of different H-induced structures coexist in broad regions of the temperature- coverage (T-theta) phase diagram.
