Structural pathways for ultrafast melting of optically excited thin polycrystalline Palladium films
Jerzy Antonowicz, Adam Olczak, Klaus Sokolowski-Tinten +28
Due to its extremely short timescale, the non-equilibrium melting of metals is exceptionally difficult to probe experimentally. The knowledge of melting mechanisms is thus based ma…
Ultrafast two-colour X-ray emission spectroscopy reveals excited state landscape in a base metal dyad
Michal Nowakowski, Marina Huber-Gedert, Hossam Elgabarty +15
Effective photoinduced charge transfer makes molecular bimetallic assemblies attractive for applications as active light induced proton reduction systems. For a more sustainable fu…
Structural changes across thermodynamic maxima in supercooled liquid tellurium: a water-like scenario
Peihao Sun, Giulio Monaco, Peter Zalden +10
Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K be…
Photo-induced plasmon-phonon coupling in PbTe
M. P. Jiang, M. Trigo, S. Fahy +19
We report the observation of photo-induced plasmon-phonon coupled modes in the group IV-VI semiconductor PbTe using Fourier-transform inelastic X-ray scattering at the Linac Cohere…
Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins
Dominik Kinschel, Camila Bacellar, Oliviero Cannelli +26
In haemoglobin (consisting of four globular myoglobin-like subunits), the change from the low-spin (LS) hexacoordinated haem to the high spin (HS) pentacoordinated domed form upon…
Ultrafast terahertz-field-driven ionic response in ferroelectric BaTiO
F. Chen, Y. Zhu, S. Liu +31
The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and function…
Picosecond electric-field-induced threshold switching in phase-change materials
Peter Zalden, Michael J. Shu, Frank Chen +16
Many chalcogenide glasses undergo a breakdown in electronic resistance above a critical field strength. Known as threshold switching, this mechanism enables field-induced crystalli…
Half-percent terahertz generation efficiency from cryogenically cooled lithium niobate pumped by Ti:sapphire laser pulses
Xiaojun Wu, Koustuban Ravi, Wenqian Ronny Huang +6
We obtained an optical-to-terahertz (THz) energy conversion efficiency of 0.5% using the tilted-pulse-front technique in lithium niobate at a cryogenically cooled temperature of 10…
Photoinduced suppression of the ferroelectric instability in PbTe
M. P. Jiang, M. Trigo, S. Fahy +18
The interactions between electrons and phonons drive a large array of technologically relevant material properties including ferroelectricity, thermoelectricity, and phase-change b…
