Possible explanation of the plateau width in the quantum hall effect at finite temperature

Abstract

The finite width of the plateau in the Hall resistance is studied quantitatively. If we gave a filling factor V , the ratio of the plateau width L I B to the center of the plateau BH square is constant f o r all other filling factors V' i j u'=u+m with m any integer. The temperature dependence of the plateau, width is also studied. Theoretical results ase in goad agreement with the data obtained j r o m expe ram e nt .
