Deskripsi
Atomically differentiating surface and subsurface is experimentally challenging. Here, the authors use in-situ electron microscopy to simultaneously monitor the surface and subsurface and show that H2 oxidation on CuO surfaces induces cycles of ordering and disordering of oxygen vacancies in the subsurface.
