Spin Hall angle in single-layer graphene

Juliana M. da Silva, Fernando A. F. Santana, Jorge G. G. S. Ramos +1

We investigate the spin Hall effect in a single-layer graphene device with disorder and interface-induced spin-orbit coupling. Our graphene device is connected to four semi-infinit…

Effect of proximity-induced spin-orbit coupling in graphene mesoscopic billiards

Anderson L. R. Barbosa, Jorge Gabriel G. S. Ramos, Aires Ferreira

Van der Waals heterostructures based on two-dimensional materials have recently become a very active topic of research in spintronics, both aiming at a fundamental description of s…

Conductance Peak Density in Disordered Graphene Topological Insulators

Louis G. C. S. Sá, A. L. R. Barbosa, J. G. G. S. Ramos

We investigate the universal properties of quantum transport in graphene nanowires that engender subtle universal conductance fluctuations. We present results for three of the main…

Spin Hall angle fluctuations in a disorder device

F. A. F. Santana, J. M. da Silva, T. C. Vasconcelos +2

We investigate a disorderly mesoscopic device that supports spin-orbit interaction. The systemis connected to four semi-infinite leads embedded in the Landauer-Buttiker setup for q…

Klein Paradox in Chaotic Dirac Billiards

A. F. M. Rodrigues da Silva, M. S. M. Barros, A. J. Nascimento Júnior +2

We investigate the Schrödinger (non-relativistic) and the Dirac (``relativistic") billiards in the universal regime. The study is based on a non-ideal quantum resonant scattering n…

Conductance Peak Density in Nanowires

T. Verçosa, Yong-Joo Doh, J. G. G. S. Ramos +1

We present a complete numerical calculation and an experimental data analysis of the universal conductance fluctuations in quasi-one-dimension nanowires. The conductance peak densi…
