- 論文の詳細を見る
We have experimentally studied metal-insulator transitions in a two-dimensional electron system in Si-MOSFET's in a magnetic field and derived a phase diagram on a ν(Landau level filling factor) vs. disorder (resistivity in the absence of magnetic field) plane. Structures of stabilized phase boundaries at ν=1 and ν=2 are discussed based on many-body enhancement of valley- and Zeeman-splitting, respectively.
