They were synthesized in a one-pot reaction using the appropriate phosphine chloride, lithium n-propylamide and chalcogen.
Although it is well known that hydrazine is generally not a good solvent for metal chalcogenides, the presence of the extra chalcogen atoms both improves the solubility and enables control over the film's final composition and grain structure.
Chalcogen (say: CAL-ko-gin) refers to four chemical elements in one column of the periodic table -- oxygen, sulfur, selenium and tellurium.
Etching and polishing of the material with chalcogens can change the material's composition, due to the motion of the tellurium atoms," explained Zhou.
