Coherently coupled carrier and phonon dynamics in elemental tellurium probed by extreme ultraviolet transient absorption
The authors utilize here a broadband extreme ultraviolet probe and a near-infrared pump to study coherent phonon and carrier dynamics in the elemental semiconductor tellurium. By measuring transitions from the tellurium 4$d$ semicore levels to the conduction band, they find that coherent phonon motion couples coherently with the hot holes and electrons. This results in an anticorrelation between the phonon-induced displacement and the electronic temperature. These findings provide insight into the coupling between the lattice and electronic structure in tellurium.
