Bonding states underpinning structural transitions in IrTe observed with micro-ARPES
C. W. Nicholson, M. D. Watson, A. Pulkkinen +6
Competing interactions in low-dimensional materials can produce nearly degenerate electronic and structural phases. We investigate the staircase of structural phase transitions in…
Persistence of structural distortion and bulk band Rashba splitting in SnTe above its ferroelectric critical temperature
Frédéric Chassot, Aki Pulkkinen, Geoffroy Kremer +8
The ferroelectric semiconductor -SnTe has been regarded as a topological crystalline insulator and the dispersion of its surface states has been intensively measured with angle-…
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…
Break of symmetry at the surface of IrTe upon phase transition measured by X-ray photoelectron diffraction
Maxime Rumo, Aki Pulkkinen, KeYuan Ma +3
IrTe undergoes a series of charge-ordered phase transitions below room temperature that are characterized by the formation of stripes of Ir dimers of different periodicities. F…
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…
