摘要
Intravalley exchange and correlation are found to induce a first-order transition at low densities in the inversion layer, lowering the valley degeneracy. For the n channel on Si(100) surface, the reduction from two valleys to one occurs roughly below 3×1011 cm-2. The one-valley phase with domain structure yields activated conductivity and other observed low-density behavior. © 1979 The American Physical Society.
