Hall Effect Measurement: Hall Bar and Van der Pauw Geometry
xiaoshanxu.unl.eduMay 20, 2016 · Hall Effect Measurements Hall effect measurements commonly use two sample geometries: Long, narrow Hall bar geometries and Nearly square or circular van der Pauw geometries. Each has advantages and disadvantages. In both types of samples, a Hall voltage is developed perpendicular to a current and an applied magnetic flux.

All materials, on the other hand, have dielectric properties, so the focus of this discussion will mostly be on permittivity measurements. 7 R 0 L 0 ' ' L L L L = = µ µ
