Graphene based magnetic hole sensor for fluid flow analysis at nanoscale level

摘要

To provide a method and apparatus for performing fluid flow analysis at a nanoscale level.SOLUTION: A method of detecting a particle comprises: magnetizing a particle using an AC magnetic field; generating an AC voltage in a sensing device having a conductive substantially 2-dimensional lattice structure from the magnetized particle; superimposing a DC magnetic field on the generated AC voltage in the sensing device; and measuring an AC Hall voltage at the sensing device.SELECTED DRAWING: Figure 15
