Imaging of low-compressibility strips in the quantum Hall liquid
Published
Journal Article
Using subsurface charge accumulation scanning microscopy, we image strips of low compressibility corresponding to several integer quantum Hall filling factors. We study in detail the strips at Landau level filling factors (Formula presented) and 4. The observed strips appear significantly wider than predicted by theory. We present a model accounting for the discrepancy by considering a disorder-induced nonzero density of states in the cyclotron gap. © 2000 The American Physical Society.
