The p-type Ag0.208Sb0.275Te0.517 boule was unidirectionally grown using a Bridgman furnace and, it was subsequently cooled rapidly by an Ar flush to form a high temperature phase AgSbTe2, which could be desirable for power generation. Though the boul

Sintered PbTe materials with average grain sizes of 28-309 μm were prepared by the spark plasma sintering technique. The apparent densities of the sintered PbTe were 8.17-8.23 Mg/m 3 , which were higher than 99% of the theoretical one. Thermoelectri

It is important to control dopant concentration with different amount for n-type PbTe thermoelement with graded structure. It was clarified that the starting materials by a gas transport method have quite homogeneous thermoelectric properties. PbTe s

A physical vapor transport technique was performed to grow an n-type PbTe single crystal heavily doped with PbI 2 . The boules obtained repeatedly by this transport were hemispheres with a dimension of 19 mm in diameter. Laue back-reflection techniqu

The resistivities ρ of the solidified n- and p-type PbTe and plasma activated sintered n-type PbTe were measured as a function of temperature during heating and cooling cycles to progressively higher temperatures until 903K in Ar atmosphere. The hys

PbTe single crystals were prepared by the Bridgman method, where either Ag 2 Te or PbI 2 was doped as the source material of silver or iodine. The hole concentration was successfully controlled in the range from 2.0 x 10 24 to 9.0 x 10 24 m -3 by dop

Pb1-xSnxTe (0≤x≤0.25) doped with different amount of PbI2 ranging from 0 to 0.4wt% were prepared by stirring melt mixtures and unidirectional solidifying using PbTe and SnTe. The thermal conductivity of the Pb0.75Sn0.25Te doped with 0.04wt% PbI2
