Title:
   Phase separation in the two-dimensional electron liquid in MOSFETs

Abstract:
We show that the existence of an intermediate phase between the Fermi liquid and
the Wigner crystal phases is a generic property of the two-dimensional pure
electron liquid in MOSFET's at zero temperature.  The physical reason for the
existence of the phases is a partial separation of the uniform phases.  We
discuss properties of these phases and a possible explanation of experimental
results on transport properties of low density electron gas in MOSFET's.  We
also argue that in certain range of parameters the partial phase separation
corresponds to a supersolid phase discussed by Andreev and Lifshitz.
