Coherent energy exchange between carriers and phonons in Peierls-distorted bismuth unveiled by broadband XUV pulses
Romain Géneaux, Iurii Timrov, Christopher J. Kaplan +3
In Peierls-distorted materials, photoexcitation leads to a strongly coupled transient response between structural and electronic degrees of freedom, always measured independently o…
Attosecond time-domain measurement of core-excitonic decay in magnesium oxide
Romain Géneaux, Christopher J. Kaplan, Lun Yue +11
Excitation of ionic solids with extreme ultraviolet pulses creates localized core-excitons, which in some cases couple strongly to the lattice. Here, core-excitonic states of magne…
Hot Phonon and Carrier Relaxation in Si(100) Determined by Transient Extreme Ultraviolet Spectroscopy
Scott K. Cushing, Michael Zürch, Peter M. Kraus +5
The thermalization of hot carriers and phonons gives direct insight into the scattering processes that mediate electrical and thermal transport. Obtaining the scattering rates for…
Direct and Simultaneous Observation of Ultrafast Electron and Hole Dynamics in Germanium
Michael Zürch, Hung-Tzu Chang, Lauren J. Borja +10
Understanding excited carrier dynamics in semiconductors is crucial for the development of photovoltaics and efficient photonic devices. However, overlapping spectral features in o…
