Photoelectron diffraction investigation of the structure of the clean TiO2(110)(1×1) surface [PDF]

, 2007
The surface relaxations of the rutile TiO2(110)(1×1) clean surface have been determined by O 1 s and Ti 2p3∕2 scanned-energy mode photoelectron diffraction. The results are in excellent agreement with recent low-energy electron diffraction (LEED) and

Three-Fold Diffraction Symmetry in Epitaxial Graphene and the SiC Substrate

, 2011
The crystallographic symmetries and spatial distribution of stacking domains in graphene films on SiC have been studied by low energy electron diffraction (LEED) and dark field imaging in a low energy electron microscope (LEEM). We find that the graphene

High bunch charge low-energy electron streak diffraction

Structural Dynamics
For time-resolved diffraction studies of irreversible structural dynamics upon photoexcitation, there are constraints on the number of perturbation cycles due to thermal effects and accumulated strain, which impact the degree of crystal order and spatial
