KBiMS4 (M=Si, Ge): Synthesis, structure, and electronic structure

Sn2SiS4, synthesis, structure, optical and electronic properties

“…Recently, metal chalcogenides containing the group 14 elements, in particular the Sn metal, have received increasing interest [1][2][3][4][5][6][7][8][9][10][11]. Sn atom can be stabilized at both the +2 oxidation state with an electron lone pair and the +4 oxidation states without the lone pair electrons in chalcogenides.…”

Syntheses and characterization of two new selenides Ba5Al2Se8 and Ba5Ga2Se8

“…Chalcogenides are an interesting class of materials with amazing structural complexity [1][2][3][4][5][6] and important properties including thermoelectricity [7][8][9][10], magnetic property [11][12][13][14], nonlinear optical property [15,16], photovoltaicity [17], superconductivity [18], and luminescent property [19,20]. In the past years, many ternary chalcogenides in the A/M/Q system (A = alkaline-earth metal; M = Al, Ga, In; Q = S, Se, Te) have been discovered and studied, including the large family of the AM 2 Q 4 compounds [21][22][23][24][25], the A 2 M 2 Q 5 compounds [26], Ba 5 Ga 2 S 8 [27], Ba 4 Ga 2 S 7 [28], Ba 3 Ga 2 S 6 [28], and Mg 5 Al 2 Se 8 [29].…”
