| Outline of Final Research Achievements |
Silver coated Si powder was synthesized and the Seebeck coefficient of the powder was successfully measured with the equipment developed in the present study. Although the result indicated that influence of semiconductor/metal interface on the Seebeck coefficient wasn’t observed in the Si/Ag system, the equipment and methods for detecting the influence were successfully established. Paste for printing method was prepared using the silver coated Si powder. Conducting thick film was successfully obtained by printing technology after heating at 600 degrees C. This method is applicable for obtaining thick film of inorganic thermoelectric material.
Metallic Co2Si phase precipitated CoSi sintered body was synthesized using CoSi supersatulated solid solution. The sample in which CoSi is surrounded by precipitated Co2Si thin layer had larger Seebeck coefficient than the one containing granular Co2Si.
