Ultrafast nonlinear Hall effect in black phosphorus
Maciej Dendzik, Andrea Marini, Samuel Beaulieu +9
The nonlinear Hall effect (NHE) is a recently discovered member of the Hall effect family in which the Hall voltage shows a nonlinear behavior when a transverse electric field is a…
Roadmap on Data-Centric Materials Science
Stefan Bauer, Peter Benner, Tristan Bereau +58
Science is and always has been based on data, but the terms "data-centric" and the "4th paradigm of" materials research indicate a radical change in how information is retrieved, h…
From structure mining to unsupervised exploration of atomic octahedral networks
R. Patrick Xian, Ryan J. Morelock, Ido Hadar +2
Understanding the spatial arrangements of atom-centered coordination octahedra is crucial for relating structures to properties for many materials families. Traditional case-by-cas…
Orbital-resolved Observation of Singlet Fission
Alexander Neef, Samuel Beaulieu, Sebastian Hammer +8
Singlet fission may boost photovoltaic efficiency [by transforming a singlet exciton into two triplet excitons and thereby doubling the number of excited charge carriers. The prima…
Excited-state band structure mapping
M. Puppin, C. W. Nicholson, C. Monney +10
Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it r…
Observation of ultrafast interfacial Meitner-Auger energy transfer in a van der Waals heterostructure
Shuo Dong, Samuel Beaulieu, Malte Selig +23
Atomically thin layered van der Waals heterostructures feature exotic and emergent optoelectronic properties. With growing interest in these novel quantum materials, the microscopi…
Scalable multicomponent spectral analysis for high-throughput data annotation
Rui Patrick Xian, Ralph Ernstorfer, Philipp Michael Pelz
Orchestrating parametric fitting of multicomponent spectra at scale is an essential yet underappreciated task in high-throughput quantification of materials and chemical compositio…
Machine Learning on Neutron and X-Ray Scattering
Zhantao Chen, Nina Andrejevic, Nathan Drucker +8
Neutron and X-ray scattering represent two state-of-the-art materials characterization techniques that measure materials' structural and dynamical properties with high precision. T…
Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
Evidence of large polarons in photoemission band mapping of the perovskite semiconductor CsPbBr
M. Puppin, S. Polishchuk, N. Colonna +16
Lead-halide perovskite (LHP) semiconductors are emergent optoelectronic materials with outstanding transport properties which are not yet fully understood. We find signatures of la…
Time- and momentum-resolved photoemission studies using time-of-flight momentum microscopy at a free-electron laser
Dmytro Kutnyakhov, Rui Patrick Xian, Maciej Dendzik +38
Time-resolved photoemission with ultrafast pump and probe pulses is an emerging technique with wide application potential. Real-time recording of non-equilibrium electronic process…
