Photon-assisted ultrafast electron-hole plasma expansion in direct band semiconductors
T. Troha, F. Klimovič, T. Ostatnický +2
Time-resolved terahertz spectroscopy is used to investigate formation and ultrafast long-distance propagation of electron-hole plasma in strongly photoexcited GaAs and InP. The obs…
Nanoscale Terahertz Conductivity and Ultrafast Dynamics of Terahertz Plasmons in Periodic Arrays of Epitaxial Graphene Nanoribbons
Arvind Singh, Hynek Němec, Jan Kunc +1
Dynamics of plasmons in nanoribbons of (hydrogen intercalated) quasi-free-standing single layer graphene is studied by terahertz spectroscopy both in the steady state and upon phot…
Ultrafast terahertz conductivity in epitaxial graphene nanoribbons: an interplay between photoexcited and secondary hot carriers
Arvind Singh, Hynek Němec, Jan Kunc +1
Optical pump-terahertz probe spectroscopy has been used to investigate ultrafast photo-induced charge carrier transport in 3.4 m wide graphene ribbons upon scaling the optical p…
THz and infrared studies of multiferroic hexagonal Y_(1-x)Eu_xMnO_3 (x=0 - 0.2) ceramics
V. Goian, S. Kamba, C. Kadlec +5
We report an investigation of hexagonal Y_(1-x)Eu_xMnO_3 ceramics with x=0, 0.1 and 0.2 using infrared and THz spectroscopies in the temperature range between 5 and 900 K. The temp…
