Phase relations in the Ag2S–CdS–SnS2 system and the crystal structure of the compounds

Morphological and thermal properties of β-SnS2 sprayed thin films using Boubaker polynomials expansion

“…Moreover, using optical measurement based on the reflectance and transmittance allows us to reach the band gap energy which is of the order of 2.65 eV. This value is in concordance with several recent yielded values [27][28][29][30] of studies. In the same way, the thermal properties of this material have been studied through an original protocol which brought photothermal and numerical analyses together.…”

The Ag2S–In2S3–Si(Ge)S2 systems and crystal structure of quaternary sulfides Ag2In2Si(Ge)S6

“…Such an approach was used in Refs. [67,68]; it is used for the tetrahedral compounds exclusively [69]. Cadmium in ternary compounds has the size intermediate between that of Ag and In.…”

Crystal structure of the new quaternary copper manganese and zirconium chalcogenides

“…This classification also holds true for divalent cations of Group IIb (B II = Zn, Cd, Hg) [3][4][5][6][7][8][9][10][11]. The exceptions are the Cu 2 HgSnS 4 structure [9], the unit cell symmetry of which is lower than stannite and is described as a vacancy-ordered structure SG I 4 , and Ag 2 CdSnS 4 where the positions of atoms correspond to an orthorhombic structure with SG Cmc2 1 [12]. The ratio of cations to anions in the discussed structure is 1:1 [13].…”
