AgTlTe—Etude de la zone de solution solide et de ses modifications structurales

Extremely low thermal conductivity of AgTlTe

“…The lattice parameters of AgTlTe evaluated from the X-ray diffraction pattern are summarized in Table 1. These values almost agree with those in literature [16]. The bulk density of the sample is about 90% of the theoretical density.…”

“…1, together with literature data [16]. It is shown that a single phase of AgTlTe with the space group Pnma is obtained in the present study.…”

Thermoelectric Properties of Ag-Tl-Te Ternary System

“…Te 2 consists of a monoclinic crystal system with space group P21/c. The upper figures indicate the results obtained in the present study and the lower figures indicate literature data[8][9][10][11]. Ag 8 Tl 2 Te 5 exhibits a cubic crystal system with space group Fm3m, in which the lattice parameter is 1.8725 nm.…”

“…Thermal diffusivity Figure 2 shows the XRD patterns of AgTl 3 Te 2 , AgTlTe, Ag 8 Tl 2 Te 5 and Ag 9 TlTe 5 , together with the literature data [8][9][10][11]. Thermal diffusivity Figure 2 shows the XRD patterns of AgTl 3 Te 2 , AgTlTe, Ag 8 Tl 2 Te 5 and Ag 9 TlTe 5 , together with the literature data [8][9][10][11].…”
