Abstract:

Seebeck coefficient, Hall effect and resistivity measurements were made on numerous compositions derived from the dichalcogenides MoSe2, MoTe2 and WSe2. Crystallographic data and thermal conductivities were available from earlier work. The composition W.99Ta.01Se2 shows the most practical promise of the systems investigated to date, with a Figure of Merit of 0.7 x 0.001deg. It is planned to study more complex solid solutions next. Concurrent work on the construction of a simple thermoelectric generator for efficiency and life tests dealt with encapsulation problems, which were partially solved by the use of chemically-setting Sauereisen cements.
