The series of Pb9.6Sb0.2Te10 - x Se x compounds with different Se content (x) were prepared, and their structure was investigated at the atomic and nanosized regime level. Thermoelectric properties were measured in the temperature range from 300 to 700 K. The Pb9.6Sb0.2Te10 - x Se x series was desig...
