Ultrafast dynamics and phonon softening in Fe1+ySe1−xTex single crystals

Ultrafast dynamics and phonon softening in Fe1+ySe1−xTex single crystals

The ultrafast quasiparticle dynamics of Fe _1+ _y Se _1− _x Te _x single crystals were investigated by dual-color transient reflectivity measurements (Δ R / R ) from 4.3 to 290 K. The electron–phonon coupling strength λ (=0.16–0.01) and the temperature-dependent energy of longitudinal-acoustic phon...
