Molecular movies: Ultrafast measurements on structural dynamics of crystals and technology developments in ultrafast science

Molecular movies : ultrafast measurements on structural dynamics of crystals and technology developments in ultrafast science Ultrafast science is an exciting physics field, enabling us to observe atoms moving within matter upon photo-excitation. Using electron 'probe' pulses and laser 'pump' pulses, we monitor dynamics in remarkable short time scales (10-15/s) with microscopic precision (10-11/m). We investigate an ultrafast insulator-to-metal transition in TSe2 and TaSe2 crystals.
