Photoinduced suppression of the ferroelectric instability in PbTe
M. P. Jiang, M. Trigo, S. Fahy +18
The interactions between electrons and phonons drive a large array of technologically relevant material properties including ferroelectricity, thermoelectricity, and phase-change b…
Free-carrier relaxation and lattice heating in photoexcited bismuth thin films
Y. M. Sheu, Y. J. Chien, C. Uher +2
We report ultrafast surface pump and interface probe experiments on photoexcited carrier transport across single crystal bismuth films on sapphire. The film thickness is sufficient…
Supersonic strain front driven by a dense electron-hole plasma
M. F. DeCamp, D. A. Reis, A. Cavalieri +11
We study coherent strain in (001) Ge generated by an ultrafast laser-initiated high density electron-hole plasma. The resultant coherent pulse is probed by time-resolved x-ray diff…
Calculations of the A_1 phonon frequency in photoexcited Tellurium
P. Tangney, S. Fahy
Calculations of the A_1 phonon frequency in photoexcited tellurium are presented. The phonon frequency as a function of photoexcited carrier density and phonon amplitude is determi…
