DOIAbstract
The specific heat Cp of glassy Ge20Se80-xBix (0 ≤ × ≤ 12) samples is investigated. The Cp at 323K and the ΔCp at glass transition temperature Tg1 show anomalous features around x=8 at.%, where p-n conduction type inversion also take place. These features are discussed in the light of Phillips model of phase separation in these glasses at the microscopic level
