Electronic and structural fingerprints of charge density wave excitations in extreme ultraviolet transient absorption spectroscopy
Tobias Heinrich, Hung-Tzu Chang, Sergey Zayko +3
Femtosecond core-level transient absorption spectroscopy is utilized to investigate photoinduced dynamics of the charge density wave in 1T-TiSe2 at the Ti M2,3 edge (30-50 eV). Pho…
Characterization of Carrier Cooling Bottleneck in Silicon Nanoparticles by Extreme Ultraviolet (XUV) Transient Absorption Spectroscopy
Ilana J. Porter, Angela Lee, Scott K. Cushing +4
Silicon nanoparticles have the promise to surpass the theoretical efficiency limit of single-junction silicon photovoltaics by the creation of a "phonon bottleneck", a theorized sl…
Solid-state core-exciton dynamics in NaCl observed by tabletop attosecond four-wave mixing spectroscopy
James D Gaynor, Ashley P Fidler, Yen-Cheng Lin +4
Nonlinear wave-mixing in solids with ultrafast x-rays can provide new insight into complex electronic dynamics of materials. Here, tabletop-based attosecond noncollinear four-wave…
Coupled Valence Carrier and Core-Exciton Dynamics in WS Probed by Few-Femtosecond Extreme Ultraviolet Transient Absorption Spectroscopy
Hung-Tzu Chang, Alexander Guggenmos, Christopher T. Chen +7
Few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy, performed with optical 500-1000 nm supercontinuum and broadband XUV pulses (30-50 eV), simultaneously p…
Simultaneous Observation of Carrier-Specific Redistribution and Coherent Lattice Dynamics in 2H-MoTe with Femtosecond Core-Level Spectroscopy
Andrew R. Attar, Hung-Tzu Chang, Alexander Britz +12
We employ few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy to reveal simultaneously the intra- and interband carrier relaxation and the light-induced str…
Source noise suppression in attosecond transient absorption spectroscopy by edge-pixel referencing
Romain Géneaux, Hung-Tzu Chang, Adam M. Schwartzberg +1
Attosecond transient absorption spectroscopy (ATAS) is used to observe photoexcited dynamics with outstanding time resolution. The main experimental challenge of this technique is…
