Beschreibung:
Due to their reduced dimensionality, surfaces and quasi two-dimensional materials exhibit numerous intriguing physical phenomena that drastically differ from the bulk. To resolve these effects and the associated dynamics at their intrinsic timescales requires experimental methodologies combining a high surface sensitivity with the essential temporal resolution. However, to date, there are still very few methods that facilitate investigation of the structural degrees of freedom of surfaces on the atomic scale along with a temporal resolution of femtoseconds or picoseconds. Addressing these c...
