Femtosecond laser patterning of graphene electrodes for thin-film transistors
Maren Kasischke, Ersoy Subaşı, Claudia Bock +4
The aim of this study is to assess femtosecond laser patterning of graphene in air and in vacuum for the application as source and drain electrodes in thin-film transistors (TFTs).…
Strong Coupling of Intersubband Resonance in a High Electron Mobility Transistor Structure to a THz Metamaterial by Ultrawide Electrical Tuning
Shovon Pal, Hanond Nong, Sergej Markmann +8
The interaction between intersubband resonances (ISRs) and metamaterial microcavities can form a strongly coupled system where new resonances form that depend on the coupling stren…
Mode-filtered electron injection into a waveguide interferometer
Sven S. Buchholz, Ulrich Kunze, Saskia F. Fischer +2
Injection of mode-filtered electrons into a phase-sensitive four-terminal waveguide Aharonov-Bohm (AB) ring is studied. An individually tuneable quantum point contact (QPC) in a wa…
Phase shifts and phase -jumps in four-terminal waveguide Aharonov-Bohm interferometers
Christoph Kreisbeck, Tobias Kramer, Sven S. Buchholz +4
Quantum coherent properties of electrons can be studied in Aharonov-Bohm (AB) interferometers. We investigate both experimentally and theoretically the transmission phase evolution…
Control of the transmission phase in an asymmetric four-terminal Aharonov-Bohm interferometer
Sven S. Buchholz, Saskia F. Fischer, Ulrich Kunze +3
Phase sensitivity and thermal dephasing in coherent electron transport in quasi one-dimensional (1D) waveguide rings of an asymmetric four-terminal geometry are studied by magnetot…
Low-temperature ballistic transport in nanoscale epitaxial graphene cross junctions
S. Weingart, C. Bock, U. Kunze +3
We report on the observation of inertial-ballistic transport in nanoscale cross junctions fabricated from epitaxial graphene grown on SiC(0001). Ballistic transport is indicated by…
