Hall Effect Experiment - University of Tennessee
www.phys.utk.edusystems, at very low temperature and large fields, the Hall resistance show a step-like (rather than linear) dependence on B. These steps are completely independent of the type of sample and quantitized to values h/e2m, where m is an integer. This is the famous Quantum Hall Effect4. The fundamental quantum of Hall resistance is h/e2 =25,813Ω ...
