Stability of all-CVD h-BN/Graphene/h-BN Hall sensors over time in ambient environment. (a) Hall voltage as a function of magnetic field and (b) time at different applied magnetic fields at 293 K after keeping the device in ambient environment for 1 day (black), 22 days (red), 49 days (blue) and 190 days (green). (c) Current-related Hall sensitivity SI over time.
