Transition to the Hall Insulator (HI)

Same sample as shown in previous example. This animation demonstrates a field sweep to higher fields starting at the n=1 plateau. In this case just the 1st LL is involved. At the beginning the same happens as in the previous example, namely the stripes get wider and finally cover the whole sample area. However, as the potential profile turns to longitudinal, there is no other lower LL which would like to keep the edge potential and therefore the potential drop between the longitudinal voltage probes can fully develop. This leads to a monotonous increase of  Rxx without peak behavior. It is important to realize, that in this regime Rxy tends to stay on the n=1 plateau while Rxx already steeply rises. This behavior is known as the "Quanten-Hall-Liquid - to - Insulator" transition. The reason for the deviation of Rxx at highest fields is the discrete numerical representation, which always contains some deviation from an ideal geometry, like in real samples.
