Far-infrared absorption and the metal-to-insulator transition in hole-doped cuprates
S. Lupi, D. Nicoletti, O. Limaj +5
By studying the optical conductivity of BSLCO and YCBCO, we show that the metal-to-insulator transition (MIT) in these hole-doped cuprates is driven by the opening of a small gap a…
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…
Sub-THz electrodynamics of the graphene-like superconductor CaAlSi
S. Lupi, L. Baldassarre, M. Ortolani +7
We report the first optical study of CaAlSi, a superconductor which displays both the crystal structure of MgB2 and the electronic band structure of intercalated graphites. The ref…
Low-energy electrodynamics of superconducting diamond
M. Ortolani, S. Lupi, L. Baldassarre +6
Heavily-boron-doped diamond films become superconducting with critical temperatures well above 4 K. Here we first measure the reflectivity of such a film down to 5 cm,…
Infrared properties of MgAlBC) single crystals in the normal and superconducting state
D. Di Castro, M. Ortolani, E. Cappelluti +3
The reflectivity of -oriented MgAl(BC) single crystals has been measured by means of infrared microspectroscopy for cm$^{-1}…
Effects of Superconductivity and Charge Order on the sub-Terahertz reflectivity of LaBaSrCuO
M. Ortolani, P. Calvani, S. Lupi +4
The reflectivity of both the plane and the c axis of two single crystals of LaBaSrCuO has been measured down to 5 cm, using cohe…
