Our work on ‘Membrane phononic crystals for high-Q_m mechanical defect modes at MHz frequencies in piezoelectric aluminum nitride‘ has now been published in Appl. Phys. Lett.

Congrats to the team and our collaborators from the University of Magdeburg!

We welcome Joram as a new PhD student to our lab! He will join the exciting adventures of our maglev team with the goal to magnetically levitate superconducting microparticles and to control their motion in the quantum regime. We wish you all the best on this journey.

Published works from our lab:

Work from our maglev team: Superconducting flip-chip devices using indium microspheres on Au-passivated Nb or NbN as under-bump metallization layer. Published in Appl. Phys. Lett. Our work made it to the cover of the journal! Congrats!

Work from our optomechanics team: Thickness dependence of the mechanical properties of piezoelectric high-Q_m nanomechanical resonators made from aluminium nitride. Published in Materials for Quantum Technologies and included in the Focus collection on Opto- and Electromechanical Systems. Congrats!

Lauren successfully defended his Master thesis at the end of 2024. His thesis is entitled Tensile-strained crystalline aluminium nitride nanomechanical resonators. Congrats and well deserved!

Yesterday Karim successfully defended his Master thesis entitled Superconducting flux transformers for the modulation of flux-tunable resonators. Congrats and well deserved!

Karim will stay with us for some months as a research engineer to support our fab efforts in the maglev experiment.
