In one embodiment, a method includes depositing a chalcogenide precursor layer onto a substrate, and annealing the precursor layer in the presence of a gaseous phase comprising volatile species, the partial pressure of each volatile species being approximately constant over substantially all of the surface of the precursor layer, the partial pressure of each species being between approximately 0.1 mTorr and 760 Torr, where the presence of the gaseous phase reduces decomposition of volatile species from the precursor layer during annealing. |
