Abstract
Systems and methods can provide a fast and accurate way to measure conductivity and Hall effect, such that transient conductivities, transient carrier densities or transient mobilities can be measured on millisecond time scales, for example. The systems and methods can also reduce the minimum magnetic field needed to extract carrier density or mobility of a given sample, and reduce the minimum mobility that can be measured with a given magnetic field.
