Single-electron double quantum dots in bilayer graphene
Luca Banszerus, Samuel Möller, Eike Icking +4
We present transport measurements through an electrostatically defined bilayer graphene double quantum dot in the single electron regime. With the help of a back gate, two split ga…
Observation of the spin-orbit gap in bilayer graphene by one-dimensional ballistic transport
L. Banszerus, B. Frohn, T. Fabian +10
We report on measurements of quantized conductance in gate-defined quantum point contacts in bilayer graphene that allow the observation of subband splittings due to spin-orbit cou…
Does carrier velocity saturation help to enhance fmax in graphene field-effect transistors?
Pedro Carlos Feijoo, Francisco Pasadas, Marlene Bonmann +10
It has been argued that current saturation in graphene field-effect transistors (GFETs) is needed to get the highest possible maximum oscillation frequency (fmax). This paper numer…
A corner reflector of graphene Dirac fermions as a phonon-scattering sensor
H. Graef, Q. Wilmart, M. Rosticher +10
Dirac fermion optics exploits the refraction of chiral fermions across optics-inspired Klein-tunneling barriers defined by high-transparency p-n junctions. We consider the corner r…
Integrated impedance bridge for absolute capacitance measurements at cryogenic temperatures and finite magnetic fields
G. J. Verbiest, H. Janssen, D. Xu +10
We developed an impedance bridge that operates at cryogenic temperatures (down to 60 mK) and in perpendicular magnetic fields up to at least 12 T. This is achieved by mounting a Ga…
