SOT Enabled 3D Magnetic Field Sensor with Low Offset and High Sensitivity
Sebastian Zeilinger, Johannes Güttinger, Klemens Prügl +10
In this work we demonstrate a spin-orbit torque (SOT) magnetic field sensor, designed as a Ta/CoFeB/MgO structure, with high sensitivity and capable of active offset compensation i…
Single device offset-free magnetic field sensing principle with tunable sensitivity and linear range based on spin-orbit-torques
Sabri Koraltan, Christin Schmitt, Florian Bruckner +12
We propose a novel device concept using spin-orbit-torques to realize a magnetic field sensor, where we eliminate the sensor offset using a differential measurement concept. We der…
Force sensitivity of multilayer graphene optomechanical devices
Peter Weber, Johannes Güttinger, Adrien Noury +2
Mechanical resonators based on low-dimensional materials are promising for force and mass sensing experiments. The force sensitivity in these ultra-light resonators is often limite…
Electro-mechanical control of an optical emitter using graphene
Antoine Reserbat-Plantey, Kevin G. Schädler, Louis Gaudreau +6
Active, in situ control of light at the nanoscale remains a challenge in modern physics and in nanophotonics in particular. A promising approach is to take advantage of the technol…
Nanotube mechanical resonators with quality factors of up to 5 million
Joel Moser, Alexander Eichler, Johannes Güttinger +2
Carbon nanotube mechanical resonators have attracted considerable interest because of their small mass, the high quality of their surface, and the pristine electronic states they h…
Raman spectroscopy on etched graphene nanoribbons
Dominik Bischoff, Johannes Güttinger, Susanne Dröscher +3
We investigate etched single-layer graphene nanoribbons with different widths ranging from 30 to 130 nm by confocal Raman spectroscopy. We show that the D-line intensity only depen…
