Measuring the Charge State of Point Defects on MgO/Ag(001)

摘要

Electron transfer processes play an important role in chemical reactions in general and in particular in catalysis. Surface defects are crucial in catalysis as oxide surfaces are often present either as supports or directly as catalysts. To understand these transfer processes at the atomic level on surfaces, one has to determine the charge state and local position of defect sites present on the surface.
