Graphene-based magnetic Hall sensor for fluid flow analysis at the nanoscale level

摘要

A method and apparatus for performing fluid flow analysis at a nanoscale level. A method for detecting particles includes magnetizing the particles using an AC magnetic field and generating an AC voltage from the magnetized particles in a sensing device having a conductive, substantially two-dimensional lattice structure. And superimposing a DC magnetic field on the generated AC voltage in the sensing device, and measuring the AC Hall voltage at the sensing device. [Selection diagram] Fig. 15
