Ultrafast measurements of mode-specific deformation potentials of BiTe and BiSe
Yijing Huang, José D. Querales-Flores, Samuel W. Teitelbaum +24
Quantifying electron-phonon interactions for the surface states of topological materials can provide key insights into surface-state transport, topological superconductivity, and p…
Ab Initio Prediction of Excited State and Polaron Effects in Transient XUV Measurements of -FeO
Isabel M. Klein, Hanzhe Liu, Danika Nimlos +2
Transient X-ray and extreme ultraviolet (XUV) spectroscopies have become invaluable tools for studying photoexcited dynamics due to their sensitivity to carrier occupations and loc…
Measuring photoexcited electron and hole dynamics in ZnTe and modeling excited state core-valence effects in transient XUV reflection spectroscopy
Hanzhe Liu, Jonathan M. Michelsen, Isabel M. Klein +1
Transient XUV spectroscopy is growing in popularity for the measurement of solar fuel and photovoltaic materials as it can separately measure electron and hole energies for multipl…
Element-specific electronic and structural dynamics using transient X-ray spectroscopy
Hanzhe Liu, Isabel M. Klein, Jonathan M. Michelsen +1
Transient X-ray absorption techniques can measure ultrafast dynamics of the elemental edges in a material or multiple layer junction, giving them immense potential for deconvolutin…
Measurements of Nonequilibrium Interatomic Forces in Photoexcited Bismuth
Samuel W. Teitelbaum, Thomas C. Henighan, Hanzhe Liu +11
We determine experimentally the excited-state interatomic forces in photoexcited bismuth. The forces are obtained by a constrained least-squares fit of the excited-state dispersion…
Coherent order parameter dynamics in SmTe
M. Trigo, P. Giraldo-Gallo, M. E. Kozina +13
We present a combined ultrafast optical pump-probe and ultrafast x-ray diffraction measurement of the CDW dynamics in SmTe at 300 K. The ultrafast x-ray diffraction measurement…
Direct Measurement of Anharmonic Decay Channels of a Coherent Phonon
Samuel W. Teitelbaum, Tom Henighan, Yijing Huang +12
We observe anharmonic decay of the photoexcited coherent A1g phonon in bismuth to points in the Brillouin zone where conservation of momentum and energy are satisfied for three-pho…
