Femtosecond X-ray Diffraction Study of Large Amplitude Coherent Optical Phonons in Laser- Excited Bismuth

Not Accessible

Your library or personal account may give you access

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.
