| Abstract: | Electrical conductivity and thermoelectric power were measured on sintered α-Sb2O4 at 250° to 780°C. Oxygen partial pressure dependence of the conductivity and sign of the Seebeck coefficient showed α-Sb2O4 to be a p -type semiconductor above 600°C in the oxygen pressure range of lo5 to 102 Pa. A hopping conduction was proposed from very small hole mobility with an activation energy of 18 kJ/mol. |
