Anderson localization in two-dimensional graphene with short-range disorder: One-parameter scaling and finite-size effects
Zheyong Fan, Andreas Uppstu, Ari Harju
We study Anderson localization in graphene with short-range disorder using the real-space Kubo-Greenwood method implemented on graphics processing units. Two models of short-range…
Obtaining localization properties efficiently using the Kubo-Greenwood formalism
Andreas Uppstu, Zheyong Fan, Ari Harju
We establish, through numerical calculations and comparisons with a recursive Green's function based implementation of the Landauer-Büttiker formalism, an efficient method for stud…
Efficient linear-scaling quantum transport calculations on graphics processing units and applications on electron transport in graphene
Zheyong Fan, Andreas Uppstu, Topi Siro +1
We implement, optimize, and validate the linear-scaling Kubo-Greenwood quantum transport simulation on graphics processing units by examining resonant scattering in graphene. We co…
Single- and multi-mode Fabry-Pérot interference in suspended graphene
Mika Oksanen, Andreas Uppstu, Antti Laitinen +5
Phase coherence of charge carriers leads to electron-wave interference in ballistic mesoscopic conductors. In graphene, such Fabry-Pérot-like interference has been observed, but a…
