The Impact

Research has been performed into baric dependences between electrical resistance and thermo-EMF of eutectic solid solutions based on cadmium diarsenide of various compositions (Cd0.97Zn0.03As2 and Cd0.95Zn0.05As2) at pressures from 16 to 50 GPa and room temperature. Pressures were created in a chamber with conducting diamond anvils that served as contacts with the sample. Structural changes were recorded by changing electrical resistance and thermo-EMF. When replacing cadmium atom, zinc forms closer bonds with arsenic, which must result in the crystal lattice strengthening and higher pressures of phase transitions. Solid solutions preserve phase transitions observed in pure cadmium diarsenide. An increase in the crystal lattice stability of the solutions is confirmed compared to initial cadmium diarsenide. It is shown that with an increase in the zinc concentration pressures of phase transitions are shifted into the zone of higher pressures. The compounds preserve electronic conductivity in the range of pressures under consideration. At pressures higher than 30 GPa the thermo-EMF values become close to zero. This may be due to both an increase on concentrations of minority charge carriers and the impact of additional donating levels in the forbidden zone of solid solutions.
