Zusammenfassung:Disclosed are methods for forming layers comprising a group 14 element, a pnictogen, and a chalcogen. In some embodiments, the group 14 element comprises germanium, the pnictogen comprises antimony, and the chalcogen comprises tellurium. The methods comprise executing a plurality of deposition cycles. A deposition cycle comprises exposing a substrate to two different group 14 precursors, to two different pnictogen precursors, or to two different chalcogen precursors. Further discloses are related systems and methods. Suitable systems include atomic layer deposition systems. Suitable devices include phase change memory devices.
