Pressure-induced structural transitions triggering dimensional crossover in lithium purple bronze Li0.9M6O17
M. K. Tran, A. Akrap, J. Levallois +7
At ambient pressure, lithium molybdenum purple bronze (Li0.9Mo6O17) is a quasi-one dimensional solid in which the anisotropic crystal structure and the linear dispersion of the und…
Infrared and Raman spectroscopy measurements of a transition in the crystal structure and a closing of the energy gap of BiTeI under pressure
M. K. Tran, J. Levallois, P. Lerch +8
BiTeI is a giant Rashba spin splitting system, in which a non-centro symmetric topological phase has recently been suggested to appear under high pressure. We investigated the opti…
Optical properties of Bi2Te2Se at ambient and high pressure
Ana Akrap, Michael Tran, Alberto Ubaldini +5
The temperature dependence of the complex optical properties of the three-dimensional topological insulator Bi2Te2Se is reported for light polarized in the a-b planes at ambient pr…
Charge dynamics of the Co-doped BaFeAs
A. Lucarelli, A. Dusza, F. Pfuner +5
We report on a thorough optical investigation over a broad spectral range and as a function of temperature of the charge dynamics in Ba(CoFe)As compounds for Co…
Temperature dependence of the excitation spectrum in the charge-density-wave ErTe and HoTe systems
F. Pfuner, P. Lerch, J. -H. Chu +3
We provide optical reflectivity data collected over a broad spectral range and as a function of temperature on the ErTe and HoTe materials, which undergo two consecutive ch…
Infrared spectroscopy of electronic bands in bilayer graphene
A. B. Kuzmenko, E. van Heumen, D. van der Marel +4
We present infrared spectra (0.1-1 eV) of electrostatically gated bilayer graphene as a function of doping and compare it with tight binding calculations. All major spectral featur…
