Quantifying inhomogeneous magnetic fields at the micron scale using Graphene Hall-Effect sensors
Lionel Petit, Thomas Blon, Benjamin Lassagne
The response of a graphene Hall-Effect sensor to the inhomogeneous magnetic field generated by a dipole located above it, is investigated numerically at room temperature as a funct…

Performance of graphene Hall effect sensors: role of bias current, disorder and Fermi velocity
Lionel Petit, Tom Fournier, Géraldine Ballon +5
Graphene Hall effect magnetic field sensors hold great promise for the development of ultra-sensitive magnetometers. Their performance is frequently analysed using the two-channel…

Raman analysis of the dehydrogenation process of hydrogenated monolayer graphene
Tom Fournier, Kelvin Cruz, Marc Monthioux +5
Creating defects in graphene by hydrogenation, either to achieve hydrogen chemisorption or partial etching, is a way to open an electronic band gap in graphene. Understanding the r…
