Suppression of noise in graphene due to non-scalar mobility fluctuations induced by impurity motion
Masahiro Kamada, Weijun Zeng, Antti Laitinen +5
Low frequency resistance variations due to mobility fluctuations is one of the key factors of noise in metallic conductors. According to theory, such noise in a two-dimension…
Terahertz detection using mechanical resonators based on 2D materials
Juha Hassel, Mika Oksanen, Teemu Elo +2
We have investigated a THz detection scheme based on mixing of electrical signals in a voltage-dependent capacitance made out of suspended graphene. We have analyzed both coherent…
Microelectromechanical components in electrical metrology
Antti Manninen, Anu Karkkainen, Nadine Pesonen +2
Microelectromechanical systems (MEMS) can offer a competitive alternative for conventional technology in electrical precision measurements. This article summarises recent work in d…
Description of self-synchronization effects in distributed Josephson junction arrays using harmonic analysis and power balance
J. Hassel, L. Gronberg, P. Helisto +1
Power generation and synchronisation in Josephson junction arrays have attracted attention for a long time. This stems from fundamental interest in nonlinear coupled systems as wel…
RSFQ devices with selective dissipation for quantum information processing
J. Hassel, H. Seppa, P. Helisto
We study the possibility to use frequency dependent damping in RSFQ circuits as means to reduce dissipation and consequent decoherence in RSFQ/qubit circuits. We show that stable R…
Theory of the Bloch Oscillating Transistor
J. Hassel, H. Seppa
The Bloch oscillating transistor (BOT) is a device, where single electron current through a normal tunnel junction can be used to enhance Cooper pair current in a mesoscopic Joseph…
