High-field and high-temperature magnetoresistance reveals the superconducting behaviour of the stacking faults in multilayer graphene
Christian E. Precker, José Barzola-Quiquia, Mun K. Chan +2
In spite of 40 years of experimental studies and several theoretical proposals, an overall interpretation of the complex behavior of the magnetoresistance (MR) of multilayer graphe…
Record-Breaking Magnetoresistance at the Edge of a Microflake of Natural Graphite
Christian E. Precker, Jose Barzola-Quiquia, Pablo D. Esquinazi +5
Placing several electrodes at the edge of a micrometer-size Sri Lankan natural graphite sample at distances comparable to the size of the internal crystalline regions, we found rec…
Nonintrinsic origin of the magnetic-field-induced metal-insulator and electronic phase transitions in graphite
José Barzola-Quiquia, Pablo D. Esquinazi, Christian E. Precker +5
A detailed magnetoresistance study of bulk and microflake samples of highly oriented pyrolytic graphite with a thickness of 25 m to 23~nm reveals that the usually observed field…
Influence of Interfaces on the Transport Properties of Graphite revealed by Nanometer Thickness Reduction
Mahsa Zoraghi, José Barzola-Quiquia, Markus Stiller +2
We investigated the influence of thickness reduction on the transport properties of graphite microflakes. Using oxygen plasma etching we decreased the thickness of highly oriented…
Functionalization of atomic force microscopy Akiyama tips for magnetic force microscopy measurements
Markus Stiller, Jose Barzola-Quiquia, Pablo D. Esquinazi +4
In this work we have used focused electron beam induced deposition of cobalt to functionalize atomic force microscopy Akiyama tips for application in magnetic force microscopy. The…
Evidence for room temperature superconductivity at graphite interfaces
Pablo D. Esquinazi, Christian E. Precker, Markus Stiller +4
In the last 43 years several hints were reported suggesting the existence of granular superconductivity above room temperature in different graphite-based systems. In this paper so…
