Second ac screening step as a probe for the first-order melting transition in layered vortex matter at intermediate temperatures
Gonzalo Rumi, Pablo Pedrazzini, Hernán Pastoriza +2
We present a new probe for the first-order transition for layered vortex matter: A second step in the screening of an ac field that is independent of the frequency and amplitude of…

Microwave characterization of superconducting coplanar resonators made out of granular aluminium
Kelvin J. Ramos, Ivana Curci, Erick Potosà +4
We have designed, fabricated and characterized microwave resonators made out of thin films of granular aluminium (grAl) with different oxygen content. We extract the contribution o…

Low-Power Optical Actuation of n-GaAs Cantilevers via Surface Piezoelectric Coupling
Ayelén Prado, Diego Perez-Morelo, Leonardo Salazar Alarcón +1
The mechanical behavior of any semiconductor microstructure is inevitably coupled to light. In the case of micro mechanical resonators (MEMs), carrier generation can affect the qua…
