Adsorption sites of individual metal atoms on ultrathin MgO(100) films

Harald Brune, François Patthey, Edgar Fernandes, Fabio Donati, Zeljko Sljivancanin

We use Ca doping during growth of one- and two-monolayer-thick MgO films on Ag(100) to identify the adsorption sites of individual adatoms with scanning tunnelingmicroscopy. For thiswe combine atomic resolution images of the bare MgO layer with images of t ...

Statistical mechanical model of gas adsorption in porous crystals with dynamic moieties

Berend Smit, Cory Matthew Simon, Efrem Daniel Braun

Some nanoporous, crystalline materials possess dynamic constituents, for example, rotatable moieties. These moieties can undergo a conformation change in response to the adsorption of guest molecules, which qualitatively impacts adsorption behavior. We pos ...
