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…
Quasilinear elliptic systems with convex-concave singular terms operator
Carlos Alberto Santos, Marcos L. Carvalho, Jose V. Goncalves
This paper deals with existence of positive solutions for a class of quasilinear elliptic systems involving the -Laplacian operator and convex-concave singular terms. Our approa…
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…
Extreme thermopower anisotropy and interchain transport in the quasi-one-dimensional metal Li(0.9)Mo(6)O(17)
J. L. Cohn, S. Moshfeghyeganeh, C. A. M. dos Santos +1
Thermopower and electrical resistivity measurements transverse to the conducting chains of the quasi-one-dimensional metal Li(0.9)Mo(6)O(17) are reported in the temperature range 5…
