Evidence for a Peierls phase-transition in a three-dimensional multiple charge-density waves solid
B. Mansart, M. J. G. Cottet, T. J. Penfold +4
The effect of dimensionality on materials properties has become strikingly evident with the recent discovery of graphene. Charge ordering phenomena can be induced in one dimension…
Infrared Conductivity of Elemental Bismuth under Pressure: Evidence for an Avoided Lifshitz-Type Semimetal-Semiconductor Transition
N. P. Armitage, Riccardo Tediosi, F. Levy +3
The application of pressure to elemental bismuth reduces its conduction-valence band overlap, and results in a semimetal-semiconductor (SMSC) transition around 25 kbar. This transi…
Evidence for strongly coupled charge-density-wave ordering in three-dimensional RE5Ir4Si10 compounds by optical measurements
Riccardo Tediosi, Fabrizio Carbone, A. B. Kuzmenko +3
We report optical spectra of LuIrSi and ErIrSi, exhibiting the phenomenon of coexisting superconductivity or antiferromagnetism and charge density wav…
Charge carrier interaction with a purely electronic collective mode: Plasmarons and the infrared response of elemental bismuth
Riccardo Tediosi, N. P. Armitage, E. Giannini +1
We present a detailed optical study of single crystal bismuth using infrared reflectivity and ellipsometry. Colossal changes in the plasmon frequency are observed as a function of…
