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…
