摘要
The superfluidity of spatially separated electrons and holes and of an unbalanced two-layer electron system in a high magnetic field is considered. The temperature T-c, of the Kosterlitz-Thouless transition to a superfluid state is obtained as a function of magnetic field H and interlayer separation D. The equation of state for the magnetoexciton system in the quasiclassical regime is analyzed. The transition from excitonic phase to electron-hole phase is considered. Possible experimental manifestations of the predicted effects are briefly discussed. [S0163-1829(99)05204-2].
