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…
A circuit analysis of an in situ tunable radio-frequency quantum point contact
Thomas Müller, Theodore Choi, Sarah Hellmüller +3
A detailed analysis of the tunability of a radio-frequency quantum point contact setup using a C-LCR circuit is presented. We calculate how the series capacitance influences resona…
An in-situ tunable radio-frequency quantum point contact
Thomas Müller, Bruno Küng, Paul Studerus +5
Incorporating a variable capacitance diode into a radio-frequency matching circuit allows us to in-situ tune the resonance frequency of an RF quantum point contact, increasing the…
