Two-dimensional to bulk crossover of the WSe electronic band structure
Patrick Le Fèvre, Raphaël Salazar, Matthieu Jamet +8
Transition Metal Dichalcogenides (TMD) are layered materials obtained by stacking two-dimensional sheets weakly bonded by van der Waals interactions. In bulk TMD, band dispersions…
Carrier-Density Control of the Quantum-Confined 1-TiSe Charge-Density-Wave
T. Jaouen, A. Pulkkinen, M. Rumo +9
Using angle-resolved photoemission spectroscopy, combined with first principle and coupled self-consistent Poisson-Schrödinger calculations, we demonstrate that potassium (K) atoms…
Protection of Ising spin-orbit coupling in bulk misfit superconductors
Tomas Samuely, Darshana Wickramaratne, Martin Gmitra +16
Low-dimensional materials have remarkable properties that are distinct from their bulk counterparts. A paradigmatic example is Ising superconductivity that occurs in monolayer mate…
Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNiBC
Philipp Kurzhals, Geoffroy Kremer, Thomas Jaouen +12
Electron-phonon coupling, i.e., the scattering of lattice vibrations by electrons and vice versa, is ubiquitous in solids and can lead to emergent ground states such as superconduc…
Insensitivity of the striped charge-orders in IrTe to alkali surface doping implies their structural origin
M. Rumo, A. Pulkkinen, B. Salzmann +7
We present a combined angle-resolved photoemission spectroscopy and low-energy electron diffraction (LEED) study of the prominent transition metal dichalcogenide IrTe upon pota…
Ultrafast Dynamics of the Surface Photovoltage in Potassium Doped Black Phosphorus
G. Kremer, M. Rumo, C. Yue +6
Black phosphorus is a quasi-two-dimensional layered semiconductor with a narrow direct band gap of 0.3 eV. A giant surface Stark effect can be produced by the potassium doping of b…
Observation of a uniaxial strain-induced phase transition in the 2D topological semimetal IrTe
C. W. Nicholson, M. Rumo, A. Pulkkinen +12
Strain is ubiquitous in solid-state materials, but despite its fundamental importance and technological relevance, leveraging externally applied strain to gain control over materia…
Misfit layer compounds: a platform for heavily-doped two-dimensional transition metal dichalcogenides
Raphaël T. Leriche, Alexandra Palacio-Morales, Marco Campetella +14
Transition metal dichalcogenides (TMDs) display a rich variety of instabilities such as spin and charge orders, Ising superconductivity and topological properties. Their physical p…
Unveiling the complete dispersion of the giant Rashba split surface states of ferroelectric -GeTe(111) by alkali doping
G. Kremer, T. Jaouen, B. Salzmann +9
-GeTe(111) is a non-centrosymmetric ferroelectric material, for which a strong spin-orbit interaction gives rise to giant Rashba split states in the bulk and at the surface. The…
Examining the surface phase diagram of IrTe with photoemission
M. Rumo, C. W. Nicholson, A. Pulkkinen +13
In the transition metal dichalcogenide IrTe, low-temperature charge-ordered phase transitions involving Ir dimers lead to the occurrence of stripe phases of different periodici…
