Self-limited oxygen exchange kinetics at SnO2 surfaces

Self-limited oxygen exchange kinetics at SnO2 surfaces

The oxygen exchange at SnO 2 surfaces strongly depends on surface termination, which is affected by the oxygen chemical potential. At low oxygen chemical potential, the surface adopts its reduced termination which allows oxygen exchange, while exchange is suppressed by the stoichiometric surface ter...

Zusammenfassung:The oxygen exchange at SnO 2 surfaces strongly depends on surface termination, which is affected by the oxygen chemical potential. At low oxygen chemical potential, the surface adopts its reduced termination which allows oxygen exchange, while exchange is suppressed by the stoichiometric surface termination. Oxygen exchange is possible at reduced and suppressed at stoichiometric SnO 2 surfaces.
