Hot-Carrier Cooling in High-Quality Graphene is Intrinsically Limited by Optical Phonons
Eva A. A. Pogna, Xiaoyu Jia, Alessandro Principi +20
Many promising optoelectronic devices, such as broadband photodetectors, nonlinear frequency converters, and building blocks for data communication systems, exploit photoexcited ch…
From diffusive to ballistic transport in etched graphene constrictions and nanoribbons
Sowmya Somanchi, Bernat Terrés, Julian Peiro +5
Graphene nanoribbons and constrictions are envisaged as fundamental components of future carbon-based nanoelectronic and spintronic devices. At nanoscale, electronic effects in the…
Limitations to Carrier Mobility and Phase-Coherent Transport in Bilayer Graphene
S. Engels, B. Terrés, A. Epping +5
We present transport measurements on high-mobility bilayer graphene fully encapsulated in hexagonal boron nitride. We show two terminal quantum Hall effect measurements which exhib…
Reducing disorder in graphene nanoribbons by chemical edge modification
Jan Dauber, Bernat Terrés, Christian Volk +2
We present electronic transport measurements on etched graphene nanoribbons on silicon dioxide before and after a short hydrouoric acid (HF) treatment. We report on changes in the…
Charge detection in a bilayer graphene quantum dot
Stefan Fringes, Christian Volk, Caroline Norda +5
We show measurements on a bilayer graphene quantum dot with an integrated charge detector. The focus lies on enabling charge detection with a 30 nm wide bilayer graphene nanoribbon…
Tunable capacitive inter-dot coupling in a bilayer graphene double quantum dot
Stefan Fringes, Christian Volk, Bernat Terrés +4
We report on a double quantum dot which is formed in a width-modulated etched bilayer graphene nanoribbon. A number of lateral graphene gates enable us to tune the quantum dot ener…
Disorder induced Coulomb gaps in graphene constrictions with different aspect ratios
B. Terrés, J. Dauber, C. Volk +3
We present electron transport measurements on lithographically defined and etched graphene nanoconstrictions with different aspect ratios including different lengths (L) and widths…
