Measurements of a Quantum Dot with an Impedance-Matching On-Chip LC Resonator at GHz Frequencies
M. -C. Harabula, T. Hasler, G. Fülöp +3
We report the realization of a bonded-bridge on-chip superconducting coil and its use in impedance-matching a highly ohmic quantum dot (QD) to a measurement setup. The…
Shot noise of a quantum dot measured with GHz stub impedance matching
T. Hasler, M. Jung, V. Ranjan +3
The demand for a fast high-frequency read-out of high impedance devices, such as quantum dots, necessitates impedance matching. Here we use a resonant impedance matching circuit (a…
Clean carbon nanotubes coupled to superconducting impedance-matching circuits
V. Ranjan, G. Puebla-Hellmann, M. Jung +6
Coupling carbon nanotube devices to microwave circuits offers a significant increase in bandwidth and signal-to-noise ratio. These facilitate fast non-invasive readouts important f…
Electrolyte gate dependent high-frequency measurement of graphene field-effect transistor for sensing applications
W. Fu, M. El Abbassi, T. Hasler +8
We performed radiofrequency (RF) reflectometry measurements at 2.4 GHz on electrolyte-gated graphene field-effect transistors (GFETs) utilizing a tunable stub-matching circuit for…
