Plasmascopy of ultrafast hot charges in solids
Dmitry A. Zimin, Raja Sen, Muhammad Qasim +2
We demonstrate an electric field-resolved approach for probing ultrafast dynamics of photoinjected charges in solids. Direct access to the electric field of few-cycle pulses enable…

Unraveling energy flow mechanisms in semiconductors by ultrafast spectroscopy: Germanium as a case study
Grazia Raciti, Begoña Abad, Riccardo Dettori +8
Semiconductor materials are the foundation of modern electronics, and their functionality is dictated by the interactions between fundamental excitations occurring on (sub-)picosec…

Occurrence of the collective Ziman limit of heat transport in cubic semiconductors: scattering channels and size effects
Jelena Sjakste, Maxime Markov, Raja Sen +2
In this work, we discuss the possibility of reaching the Ziman conditions for collective heat transport in cubic bulk semiconductors, such as Si, Ge, AlAs and AlP. In natural and e…
