All-carbon vertical van der Waals heterostructures: Non-destructive functionalization of graphene for electronic applications
Miroslaw Woszczyna, Andreas Winter, Miriam Grothe +6
We present a route to non-destructive functionalization of graphene via assembly of vertical all-carbon van der Waals heterostructures. To this end, we employ singlelayer graphene…
Functional single-layer graphene sheets from aromatic monolayers
Dan G. Matei, Nils-Eike Weber, Simon Kurasch +8
We demonstrate how self-assembled monolayers of aromatic molecules on copper substrates can be converted into high-quality single-layer graphene using low-energy electron irradiati…
Precision quantization of Hall resistance in transferred graphene
Mirosław Woszczyna, Miriam Friedemann, Martin Götz +4
We show that quantum resistance standards made of transferred graphene reach the uncertainty of semiconductor devices, the current reference system in metrology. A large graphene d…
Versatile sputtering technology for Al2O3 gate insulators on graphene
M. Friedemann, M. Woszczyna, A. Müller +5
We report a novel fabrication method of graphene Al2O3 gate insulators based on sputtering. Electrical performance of dual-gated mono- and bilayer exfoliated graphene devices is pr…
Graphene p-n junction Arrays as Quantum-Hall Resistance Standards
Mirosław Woszczyna, Miriam Friedemann, Thorsten Dziomba +2
We demonstrate a device concept to fabricate resistance standards made of quantum Hall series arrays by using p-type and n-type graphene. The ambipolar nature of graphene allows fa…
Magneto-Transport Properties of Exfoliated Graphene on GaAs
Mirosław Woszczyna, Miriam Friedemann, Klaus Pierz +2
We studied the magneto-transport properties of graphene prepared by exfoliation on a III V semiconductor substrate. Tuneability of the carrier density of graphene was achieved by u…
