Multiband Superconductivity and Charge Density Wave in HfxZr1-xTe3 single crystals
F. F. G. Nogueira, M. S. da Luz, M. S. Torikachvili +3
We report on the bulk multiband superconductivity and charge density wave (CDW) in HfxZr1-xTe3 single crystals. The parent compound ZrTe3 is a layered van der Waals material that u…
Substitution modulated transition from semimetal to superconductor in ZrTeSe with coexistence of nontrivial electronic topology
V. M. Fim, C. F. Schuch, L. R. de Faria +5
This study explores the emergence of superconductivity in high-quality ZrTeSe crystals, grown via the isothermal chemical vapor transport (ICVT) technique. Resistive, s…
On the Physical Meaning of the Geometric Factor and the Effective Thickness in the Montgomery Method
F. S. Oliveira, L. M. S. Alves, M. S. da Luz +2
Simulations carried out with COMSOL software in order to study the electrical resistivity of rectangular samples are reported. The comparison of the results with the four-probe met…
Superconductivity in Te-deficient ZrTe
L. E. Correa, P. P. Ferreira, L. R. de Faria +6
We present structural, electrical, and thermoelectric potential measurements on high-quality single crystals of ZrTe grown from isothermal chemical vapor transport. These m…
A Simple and Precise Way to Determine Electrical Resistivity of Isotropic Conductors: Simplifying the Four-Probe Method
L. M. S. Alves, F. S. Oliveira, E. C. Romão +2
COMSOL Multiphysics software is used to describe the behavior of the electrical resistivity of several samples with rectangular shape typically used in the Montgomery method. The s…
On the Fermi gas, the Sommerfeld fine structure constant, and the electron-electron scattering in conductors
C. A. M. dos Santos, M. S. da Luz, F. S. Oliveira +1
Electrical energy is considered as a fundamental parameter for inclusion in Fermi gas theory, in addition to thermal energy. It is argued that electrical energy can move some elect…
Growth of Pure and Intercalated ZrTe2, TiTe2 and HfTe2 Dichalcogenide Single Crystals by Isothermal Chemical Vapor Transport
Lucas E. Correa, Leandro R. de Faria, Rennan S. Cardoso +4
We report on a modified chemical vapor transport (CVT) methodology for the growth of pure and intercalated Zr, Ti, and Hf dichalcogenide single crystals, e.g. ZrTe2, Gd0.05ZrTe2, H…
Evidence for multiband superconductivity and charge density waves in Ni-doped ZrTe
Lucas E. Correa, Pedro P. Ferreira, Leandro R. de Faria +6
We carried out a comprehensive study of the electronic, magnetic, and thermodynamic properties of Ni-doped ZrTe. High quality NiZrTe single crystals show a po…
Interplay between antiferrodistortive, ferroelectric and superconducting instabilities in Sr_{1-x}Ca_{x}$TiO_{3-δ}
B. S. de Lima, M. S. da Luz, F. S. Oliveira +11
SrTiO undergoes a cubic-to-tetragonal phase transition at 105K. This antiferrodistortive transition is believed to be in competition with incipient ferroelectricity. Substitu…
