Negative differential resistance in normal narrow bands - superconducting junctions with Andreev reflection
N. García, P. Esquinazi
We have calculated current-voltage characteristic curves for normal-superconducting junctions with Andreev reflections and different types of electronic bands. We found that when t…
Mean field superconductivity approach in two dimensions: Hydrogen in Graphite
N. García, P. Esquinazi
Within the BCS theory of superconductivity we calculate the superconducting gap at zero temperature for metallic hydrogen-graphene system in order to estimate the superconducting c…
From Ohmic to Ballistic Transport in Oriented Graphite
N. García, P. Esquinazi, J. Barzola-Quiquia +2
In this work we show that for a quasi-2D system of size and thickness the resistance goes as , diverging logarithmically with the size. Measurements in hig…
Intrinsic Superconductivity at 25 K in Highly Oriented Pyrolytic Graphite
P. Esquinazi, N. García, J. Barzola-Quiquia +6
High resolution magnetoresistance data in highly oriented pyrolytic graphite thin samples manifest non-homogenous superconductivity with critical temperature K. These…
Experimental Evidence for Two-Dimensional Magnetic Order in Proton Bombarded Graphite
J. Barzola-Quiquia, P. Esquinazi, M. Rothermel +3
We have prepared magnetic graphite samples bombarded by protons at low temperatures and low fluences to attenuate the large thermal annealing produced during irradiation. An overal…
