Journal ArticleDOI
Mesoscopic transport properties of composite fermions
A. S. Sachrajda,Y. Feng,Humberto A. Carmona,Andre K. Geim,P. C. Main,Laurence Eaves,C. T. Foxon +6 more
TL;DR: In this paper, the magnetoresistance of quantum wires, junctions and rings near Landau filling factor v = 1/2 was measured to search for effects due to composite fermions.
Journal ArticleDOI
A new detection scheme for van der Waals heterostructures, imaging individual fullerenes between graphene sheets, and controlling the vacuum in scanning transmission electron microscopy
Giacomo Argentero,Kimmo Mustonen,Rasim Mirzayev,Andreas Mittelberger,Toma Susi,Gregor T. Leuthner,Yang Cao,Mohammad Reza Ahmadpour Monazam,Timothy J. Pennycook,Clemens Mangler,Christian Kramberger,Andre K. Geim,Jani Kotakoski,Jannik C. Meyer +13 more
TL;DR: In this article, a pixelated detector for recording the scattered intensity in the angular range of the annular darkfield detector was used to reveal the deformations in a graphene-hBN heterostructure, where the two layers have only a small lattice mismatch.
Proceedings ArticleDOI
Preparation and characterisation of exfoliated graphene for quantum resistance metrology
Gert Rietveld,H. J. van Elferen,Ajm Jos Giesbers,A. Veligura,U. Zeitler,Kostya S. Novoselov,B. J. van Wees,Andre K. Geim,J.C. Maan +8 more
TL;DR: In this paper, the handling and measurement of exfoliated graphene samples have been discussed for use in quantum resistance metrology, and good progress is recently made in achieving contact resistances to graphene of less than 50 Ω.
Journal ArticleDOI
Randomly Distributed Ultrasmall Metal Particles on the Surface of High-Mobility 2deg Samples
P. Omling,Heiner Linke,K. Deppert,Lars Samuelson,Humberto A. Carmona,Andre K. Geim,P. C. Main +6 more
TL;DR: In this article, ultrasmall silver particles, 33 nm in diameter, have been deposited on the surface of modulation-doped GaAs/Al 0.33Ga0.67As samples, containing a high mobility 2DEG.

Making Graphene Luminescent
Tobias Gokus,Rahul R. Nair,A. Bonetti,Miriam Böhmler,Antonio Lombardo,K. S. Novoselov,Andre K. Geim,Andrea C. Ferrari,Achim Hartschuh +8 more
TL;DR: In this article, strong photoluminescence (PL) can be induced in single-layer graphene on using an oxygen plasma treatment, which is spatially uniform across the flakes and connected to elastic scattering spectra distinctly different from those of gapless pristine graphene.
