Abstract

The comparison of actual manganese concentration in (Hg,Mn)Te samples grown by liquid phase epitaxy on CdTe and Cd_0.96Zn_0.04Te substrates to values obtained from the phase diagram of Hg-Mn-Te system reveals considerable discrepancies. The thermodynamic analysis made in assumption that the manganese concentration in the melting is low strained solid phase and superolled liquid one, i.e. the crystallization process is affected by elastic strain in epitaxial layer caused by lattice mismatch between substrate and film. It is shown also that the model of complete association in liquid phase do not provide a good agreement with experimental data.
