TlInSe2–TlSmSe2 System

Inorganic Materials Aims and scope

Abstract

The phase diagram of the TlInSe2–TlSmSe2 system was mapped out using differential thermal analysis, microstructural examination, and x-ray diffraction data. The system was found to contain a partial solid-solution series (0–9 mol % TlSmSe2 at room temperature) and a quaternary compound of composition Tl2InSmSe4 , which melts congruently at 1250 K. The electrical conductivity and Hall coefficient of TlInSe2–TlSmSe2 alloys were measured as a function of temperature. With increasing Sm content, the lattice parameters of the solid solution increase linearly, while its band gap decreases.
