Tin Chalcogenides

Electrodeposition of nanometric SnSe layers from aqueous and non-aqueous solutions followed by annealing in order to improve their photoelectrical properties has been reported [200].

Given the toxic nature of hydrazine, it is clearly desirable to reduce the amount of hydrazine used in the spinning process. To this end, high-quality tin chalcogenide films spun using a mixture of water and hydrazine (20% hydrazine in water by volume) have also been demonstrated.47 The electrical properties of these films are comparable with those achieved from films deposited from pure hydrazine.

For the fabrication of semiconductor devices, tin chalcogenides are deposited by the thermal decomposition (MOCVD) of organotin chalcogenides R3SnXR ( X = S, Se, or Te), which must be free of any contaminants which would detract from the performance of the semiconductors. These pure precursors can be prepared by the light-induced com-proportionation of R3SnSnR3 and R XXR (equation 17-12).13 The obvious mechanism... 

The influence of various substituents on 5 Sn for series of tetra-coordinate tin(I V) compounds SnX4 n Yn (n = 0 ) can be graphically depicted as U-shaped curves. These substituent effects are not linear, but approximately pair-wise additive. Some representative Sn NMR data are given in Table 2.1.3 (tin hydrides). Table 2.1.4 (tetraorgano. tin). Table 2.1.5 (tin halides). Table 2.1.6 (tin chalcogenides), and Table 2.1.7 (compounds with Sn—N, Sn—P, Sn—As, Sn—Sb, and Sn—Bi bonds). 

Gopper-zinc-tin chalcogenide (Gu2ZnSnS4, GZTS) a copper-based quaternary chalcogenide have recently attracted a great deal of attention as a low-cost alternative to conventional absorber materials in photovoltaics.
