摘要：

We locally image the low-compressibility strip corresponding to integer Quantum Hall filling factor v = 2 and find that its width appears significantly larger than that predicted by theory. We explain this result by a disorder-induced finite density of states in the cyclotron gap. (C) 2000 Elsevier Science B.V. All Fights reserved.
