Curved Crystals

Curved crystals can be thought of as “multi-vicinal” surfaces since they have a continuously varying step-periodicity. They are very useful for the study of properties that depend on terrace width (e.g. surface electron behavior, catalytic activity, molecular adsorption…). Since all surface orientations are available in one sample, experiments with multiple planar samples and vacuum cycles are replaced by a single one-sample, one-cycle experiment.
