Ultrastable low-noise current amplifier
Dietmar Drung, Christian Krause, Ulrich Becker +2
An ultrastable low-noise current amplifier (ULCA) is presented. The ULCA is a non-cryogenic instrument based on specially designed operational amplifiers and resistor networks. It…
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…
Towards a Graphene-Based Quantum Impedance Standard
C. -C. Kalmbach, J. Schurr, F. J. Ahlers +4
Precision measurements of the quantum Hall resistance with alternating current (ac) in the kHz range were performed on epitaxial graphene in order to assess its suitability as a qu…
