Few-monolayer yttria-doped zirconia films: Segregation and phase stabilization
Peter Lackner, Amy J. Brandt, Ulrike Diebold +1
For most applications, zirconia (ZrO2) is doped with yttria. Doping leads to the stabilization of the tetragonal or cubic phase, and increased oxygen ion conductivity. Most previou…
Substoichiometric ultrathin zirconia films cause strong metal-support interaction
Peter Lackner, Joong-Il Jake Choi, Ulrike Diebold +1
The strong metal-support interaction (SMSI) leads to substantial changes of the properties of an oxide-supported catalyst after annealing under reducing conditions. The common expl…
Surface structures of ZrO films on Rh(111): From two layers to bulk termination
Peter Lackner, Zhiyu Zou, Sabrina Mayr +3
We have studied zirconia films on a Rh(111) substrate with thicknesses in the range of 2-10 monolayers (ML) using scanning tunneling microscopy (STM) and low-energy electron diffra…
Well-Ordered In Adatoms at the InO(111) Surface Created by Fe Deposition
Margareta Wagner, Peter Lackner, Steffen Seiler +7
Metal deposition on oxide surfaces usually results in adatoms, clusters, or islands of the deposited material, where defects in the surface often act as nucleation centers. Here an…
