Heterophase with inhomogeneous distribution of free carriers in GeTe
Vengalis B.Yu., Kastal'skii A.A.
A fine structure has been observed in the spectra of the plasma reflection of light from single-crystal GeTe. It is attributed to the onset of a phase transition of the "gas-liquid" type in the free hole-acceptor subsystem, with formation of a spatial inhomogeneity in the distribution of the free carriers.
