Tern�re Thallium-�bergangsmetall-Chalkogenide mit ThCr2Si2-Struktur

Synthesis and Characterization of Quaternary Sulfides with ThCr2Si2-Type Structure: KCo2−xCuxS2(0.5 ≤x≤ 1.5) andACoCuS2(A= K, Rb, Cs)

“…2a. The PXD patterns for RbCoCuS 2 and CsCo c unit cell parameter increases linearly with r A (Fig. 3), as expected.…”

“…The synthesis. Because the Rb and Cs analogs of KCoCuS 2 were prepared under similar experimental conditions, we composition of the samples was determined by inductively assume that for these compounds the actual composition ACo 2 S 2 (Table 2) shows that for the series KCo 2Ϫx Cu x S 2 (Table 2A) the difference is within the experimental error is not likely to deviate significantly from the nominal one.…”

Electrochemical Deposition of the Single Phase TlxCu3 – xSe2 Thin Films

“…2 The crystals of TlCu 2 Se 2 (TCSe) consist of layered structures, where the Tl + ions are located above and below the layers. 3,4 The unit cell can be seen in Figure 1.…”

“…3,6 Indeed, the electrical and optical properties of group I-III-VI compound films are strongly related to the film growth techniques. TCSe has been prepared by heating, in sealed silica tubes in vacuum, stoichiometric amounts of TlSe, copper and selenium 3,4 or elemental mixtures at 500 o C for 7 days. It is then formed into a pellet, and annealed at 250 o C for 7 days, followed by slow cooling.…”

Thallium dithiotricuprate(I)

“…During an investigation of the TI-Cuchalcogen systems (Klepp & Boller, 1978;Klepp, Boiler & V611enkle, 1980) a new compound of composition TICu3S 2 was found. It was prepared from TI2S, Cu and S powders which were mixed in the stoichiometric ratio and sealed into a silica capsule at 1.3 × 10 -2 Pa.…”
