Electronic properties of transition-metal dichalcogenides

Graphene is not the only prominent example of two-dimensional (2D) materials. Due to their interesting combination of high mechanical strength and optical transparency, direct bandgap and atomic scale thickness transition-metal dichalcogenides (TMDCs) are ...

Tuning the metal-insulator transition in NdNiO3 heterostructures via Fermi surface instability and spin fluctuations

Joël Mesot, Elia Razzoli, Zoran Ristic

We employed in situ pulsed laser deposition (PLD) and angle-resolved photoemission spectroscopy (ARPES) to investigate the mechanism of the metal-insulator transition (MIT) in NdNiO3 (NNO) thin films, grown on NdGaO3(110) and LaAlO3(100) substrates. In the ...

Dynamics across the structural transitions at elevated temperatures in Na0.7CoO2

Martin Mansson

The layered transition-metal oxide Nax CoO2 has been studied extensively both for its correlated electronic properties as well as for potential battery applications. It was discovered that high-temperature Na ion vacancy order and dynamics can be very usef ...

Design and implementation of a fs-Transmission Electron Microscope for time-resolved studies of strongly correlated systems and nanostructures

Luca Piazza

The integration of ultrafast laser systems with transmission electron microscopes led to the extension of conventional electron microscopy (PINEM) to the 4th dimension, time, and new techniques as photon-induced near-field electron microscopy became availa ...

Tuning electronic correlations in transition metal pnictides: Chemistry beyond the valence count

Thorsten Schmitt, Joël Mesot, Elia Razzoli, Philipp Aebi

The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the research on iron-based pnictide superconductors. Here we use soft x-ray angle-resol ...

Spin-stripe phase in a frustrated zigzag spin-1/2 chain

Helmuth Berger

Motifs of periodic modulations are encountered in a variety of natural systems, where at least two rival states are present. In strongly correlated electron systems, such behaviour has typically been associated with competition between short-and long-range ...

Duration of Purkinje cell complex spikes increases with their firing frequency

Michele Giugliano

Climbing fiber (CF) triggered complex spikes (CS) are massive depolarization bursts in the cerebellar Purkinje cell (PC), showing several high frequency spikelet components (+/- 600 Hz). Since its early observations, the CS is known to vary in shape. In th ...

Differences between magnitudes and health impacts of BC emissions across the United States using 12 km scale seasonal source apportionment

Athanasios Nenes

Recent assessments have analyzed the health impacts of PM2.5 from emissions from different locations and sectors using simplified or reduced-form air quality models. Here we present an alternative approach using the adjoint of the Community Mult ...

Magnetic excitations in soft X-ray RIXS: Recent developments

Marco Grioni, Simon Karl Moser, Sara Fatale

Resonant inelastic X-ray scattering (RIXS) has rapidly become a mature spectroscopic technique. In particular, taking advantage of an improved energy resolution, a series of experiments performed over the past 5 years have established soft X-ray RIXS as a ...

High-temperature Mott transition in wide-band-gap semiconductor quantum wells

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Raphaël Butté, Jacques Levrat, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Georg Rossbach, Mehran Shahmohammadi

The crossover from an exciton gas to an electron-hole plasma is studied in a GaN/(Al,Ga)N single quantum well by means of combined time-resolved and continuous-wave photoluminescence measurements. The two-dimensional Mott transition is found to be of conti ...
