Revealing Charge Carrier Dynamics and Transport in Te-Doped GaAsSb and GaAsSbN Nanowires by Correlating Ultrafast Terahertz Spectroscopy and Optoelectronic Characterization
Long Yuan, Rabin Pokharel, Shisir Devkota +6
Recent advances in the growth of III-V semiconductor nanowires (NWs) hold great promise for nanoscale optoelectronic device applications. Recently, it was found that a small amount…
Time-resolved Photoluminescence in Terahertz-driven Hybrid Systems of Plasmons and Excitons
Chen-Yen Lai, D. A. Yarotski, Jian-Xin Zhu
Ultrafast pump-probe technique is a powerful tool to understand and manipulate properties of materials for designing novel quantum devices. An intense, single cycle terahertz pulse…
Tracking ultrafast photocurrents in the Weyl semimetal TaAs using THz emission spectroscopy
N. Sirica, R. I. Tobey, L. X. Zhao +14
We investigate polarization-dependent ultrafast photocurrents in the Weyl semimetal TaAs using terahertz (THz) emission spectroscopy. Our results reveal that highly directional, tr…
Probing and controlling terahertz-driven structural dynamics with surface sensitivity
P. Bowlan, J. Bowlan, S. A. Trugman +8
Intense, single-cycle terahertz (THz) pulses offer a promising approach for understanding and controlling the properties of a material on an ultrafast time scale. In particular, re…
Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs
B. Xu, Y. M. Dai, L. X. Zhao +12
Strong coupling between discrete phonon and continuous electron-hole pair excitations can give rise to a pronounced asymmetry in the phonon line shape, known as the Fano resonance.…
Probing ultrafast spin dynamics in the antiferromagnetic multiferroic HoMnO through a magnon resonance
P. Bowlan, S. A. Trugman, J. Bowlan +5
We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM).…
Probing the Interplay between Quantum Charge Fluctuations and Magnetic Ordering in LuFe2O4
J. Lee, S. A. Trugman, C. D. Batista +7
Ferroelectric and ferromagnetic materials possess spontaneous electric and magnetic order, respectively, which can be switched by the corresponding applied electric and magnetic fi…
