Pressure and alloying effects on the metal to insulator transition in NiS{2-x}Se{x} studied by infrared spectroscopy
A. Perucchi, C. Marini, M. Valentini +11
The metal to insulator transition in the charge transfer NiS{2-x}Se{x} compound has been investigated through infrared reflectivity. Measurements performed by applying pressure to…
The optical phonon spectrum of SmFeAsO
C. Marini, C. Mirri, G. Profeta +12
We measured the Raman and the Infrared phonon spectrum of SmFeAsO polycrystalline samples. We also performed Density Functional Theory calculations within the pseudopotential appro…
Transport and infrared properties of SmFeAs(O1-xFx): from SDW to superconducting ordering
M. Tropeano, C. Fanciulli, C. Ferdeghini +12
We report measurements of resistivity, magnetoresistivity, Hall effect, Seebeck coefficient, infrared reflectivity of undoped SmFeAsO and lightly doped SmFeAs(O0.93F0.07) oxypnicti…
Two-band parallel conductivity at terahertz frequencies in the superconducting state of MgB.
M. Ortolani, P. Dore, D. Di Castro +7
The optical response of the two-band superconductor MgB has been studied in the 0.7-4 THz range on films with very low impurity level. The effect of the high-energy -gap is…
Quasiparticle evolution and pseudogap formation in V2O3: An infrared spectroscopy study
L. Baldassarre, A. Perucchi, D. Nicoletti +10
The infrared conductivity of V2O3 is measured in the whole phase diagram. Quasiparticles appear above the Neel temperature TN and eventually disappear further enhancing the tempera…
Electrodynamics near the Metal-to-Insulator Transition in V3O5
L. Baldassarre, A. Perucchi, E. Arcangeletti +5
The electrodynamics near the metal-to-insulator transitions (MIT) induced, in V3O5 single crystals, by both temperature (T) and pressure (P) has been studied by infrared spectrosco…
