Abstract
The mechanism of formation of an inhomogeneous ground state of weakly doped systems, consisting of the domains of metallic and insulating phases, is p roposed. According to this mechanism, the formation of the charge-neutral m etallic regions with the highest possible concentration of free charge carr iers (and hence of the dopants generating them) is shown to be thermodynami cally advantageous.
