Femtosecond lattice dynamics in photoexcited bismuth: Ultrafast optical and x-ray measurements
Long Beach, CA(2006)
Abstract
We investigate high amplitude coherent optical phonon dynamics in bismuth through femtosecond x-ray and optical scattering. From these experiments, we present the first detailed measurements of changes in the interatomic potential following high-density photoexcitation.
