Temperature dependence of the optical phonon reflection band in GaP
Nuwanjula S. Samarasingha, Stefan Zollner
We explore the effect of temperatures between 80 and 720 K on the energy and linewidth of zone-center transverse (TO) and longitudinal (LO) optical phonons in bulk gallium phosphid…

Ultrafast dynamics of hot charge carriers in an oxide semiconductor probed by femtosecond spectroscopic ellipsometry
Steffen Richter, Oliver Herrfurth, Shirly Espinoza +8
Many linked processes occur concurrently in strongly excited semiconductors, such as interband and intraband absorption, scattering of electrons and holes by the heated lattice, Pa…
