On the direct insulator-quantum Hall transition in two-dimensional electron systems in the vicinity of nanoscaled scatterers

<p>Abstract</p> <p>A direct insulator-quantum Hall (I-QH) transition corresponds to a crossover/transition from the insulating regime to a high Landau level filling factor &#957; &gt; 2 QH state. Such a transition has been attracting a great deal of both experimental and th...
