The two-phase region in 2(ZnSe)x(CuInSe2)1−x alloys and structural relation between the tetragonal and cubic phases

Electronic band gap of Zn2x(CuIn)1−xX2 solid solution series (X=S, Se, Te)

“…This composition range includes the two-phase field, where a cubic phase with x = 0.42 (X = S), x = 0.36 (X = Se) and x = 0.3 (X = Te) and a tetragonal phase with x = 0.1 (X = S, Se, Te) coexists [14][15][16]. Because of the small difference between the band gap energies of the CuInX 2 -rich end of the cubic Fig.…”

“…These samples were homogenized by a further annealing of pellets in evacuated silica tubes at T = 700 • C. More details about the sample synthesis can be found in Refs. [13][14][15][16].…”

“…For long time, it was assumed that by alloying the non-isotype II-VI and I-III-VI 2 compounds, a complete or nearly complete solid solution series [10-12] is formed. Our latest investigation revealed for all three systems a broad region, where both a tetragonal and a cubic phase coexist (two-phase field) [13][14][15][16].…”

Structural aspects of adamantine like multinary chalcogenides

“…Kinetic experiments using presynthesized samples should provide an approximation to the equilibrium, which was realized in practice by very small cooling rates. Details of the synthesis were published previously [11][12][13][14][15]17].…”

“…The work presented here will give an overview and a generalization of our detailed investigations about structure and phase relations as well as metal ordering [11][12][13][14][15]17] of adamantine multinary chalcogenides.…”
