A research cohort hailing from the Shanghai Institute of Microsystem and Information Technology, which operates under the auspices of the Chinese Academy of Sciences, has made a significant discovery. They observed that as the channel width of graphene Hall effect devices is narrowed, there is a corresponding rise in the magnetic field intensity necessary to attain quantization. Notably, they identified that a channel width of around 360 micrometers represents the sweet spot, where an optimal equilibrium is achieved.
