Abstract:

Femtosecond time-resolved X-ray diffraction was used to directly study optical phonons in laser-excited Bismuth. A periodic modulation of the diffraction efficiency reveals initially coherent lattice distortions with atomic displacements of nearly 10% of the nearest-neighbor-distance.

Femtosecond X-ray diffraction measurement of a solid-solid phase transition in VO2

SPRINGER SERIES CHEM 71 (2003) 33-35

Authors:

A Cavalleri, C Toth, CW Siders, JA Squier, F Raksi, P Forget, JC Kieffer

Abstract:

Femtosecond x-rays were for the first time used to probe a photoinduced solid-solid phase transition in VO2. The fast timescale observed suggests that, in this regime, the structural distortion may not be thermally initiated.
