Global room-temperature superconductivity in graphite
Y. V. Kopelevich, J. H. S. Torres, R. Ricardo da Silva +3
Room temperature superconductivity under normal conditions has been a major challenge of physics and material science since its very discovery. Here we report the global room-tempe…
Extraordinary magnetoresistance in graphite: experimental evidence for the time-reversal symmetry breaking
Y. Kopelevich, R. R. da Silva, A. S. Alexandrov
The ordinary magnetoresistance (MR) of doped semiconductors is positive and quadratic in a low magnetic field, B, as it should be in the framework of the Boltzmann kinetic theory o…
Possible superconductivity in multi-layer-graphene by application of a gate voltage
A. Ballestar, P. Esquinazi, J. Barzola-Quiquia +4
The carrier density in tens of nanometers thick graphite samples (multi-layer-graphene, MLG) has been modified by applying a gate voltage () perpendicular to the graphene plan…
Local and Global Superconductivity in Bismuth
Luis A. Baring, Robson R. da Silva, Yakov Kopelevich
We performed magnetization M(H,T) and magnetoresistance R(T,H) measurements on powdered (grain size ~ 149 micrometers) as well as highly oriented rhombohedral (A7) bismuth (Bi) sam…
