Terahertz radiation driven chiral edge currents in graphene
J. Karch, C. Drexler, P. Olbrich +14
We observe photocurrents induced in single layer graphene samples by illumination of the graphene edges with circularly polarized terahertz radiation at normal incidence. The photo…
Helicity-dependent photocurrents in graphene layers excited by mid-infrared radiation of a CO-laser
Chongyun Jiang, V. A. Shalygin, V. Yu. Panevin +6
We report the study of the helicity driven photocurrents in graphene excited by mid-infrared light of a CO-laser. Illuminating an unbiased monolayer sheet of graphene with circ…
Graphene, universality of the quantum Hall effect and redefinition of the SI system
T. J. B. M. Janssen, N. E. Fletcher, R. Goebel +6
The Système Internationale d'unités (SI system) is about to undergo its biggest change in half a century by redefining the units for mass and current in terms of the fundamental co…
Encapsulation and Electronic Control of Epitaxial Graphene by Photosensitive Polymers and UV light
Samuel Lara-Avila, Kasper Moth-Poulsen, Rositza Yakimova +4
Electronic devices using epitaxial graphene on Silicon Carbide require encapsulation to avoid uncontrolled doping by impurities deposited in ambient conditions. Additionally, inter…
