Electronic promoters and semiconductor oxidation: Alkali metals on Si(111) surfaces.
TL;DR: In this paper, the effect of thin overlayers of the low-electronegativity metals Cs and Na upon the oxidation of Si(111) surfaces was examined and a reevaluation of the microscopic mechanisms proposed to explain overlayer-induced oxidation promotion was presented.

Low-electronegativity overlayers and enhanced semiconductor oxidation: Sm on Si(111) and GaAs(110) surfaces
TL;DR: Thin mixed valence overlayers (1 monolayer) of Sm deposited on Si or GaAs cleavage surfaces prior to oxygen exposure give rise to oxidation promotion effects of unprecedented magnitude.

Interface chemistry of ternary semiconductors: Local morphology of the Hg 1 − x Cd x Te(110)-Cr interface
TL;DR: Synchrotron Radiation Photoemission studies of interfaces prepared in situ on cleaved substrates show atomic interdiffusion with Cr/Hg and Cr/Cd exchange reactions taking place at room temperature for Cr coverages less than 2A.

High-resolution photoemission study of the interaction of hydrogen with GaAs(110) surfaces.
TL;DR: Une etude de photoemission de radiation synchrotron de la chimisorption sur des surfaces de GaAs(110) lies in situ selon qu'au moins dans le regime a haute couverture, thesorption de l'hydrogene intervient via the formation of liaisons de surface entre l'Hydrogene atomique and les atomes d'As et Ga.

Overlayer‐induced enhanced oxidation of GaAs surfaces
TL;DR: In this paper, a synchrotron radiation photoemission investigation of the GaAs surface interaction with oxygen in the presence of Ag, Au, and Cr overlayers, and the results showed that the promotion effect is maximum in the case of Cr overlayer, and that the nature of the surface reaction products changes if oxygen or water is employed.
