Abstract:
1. A method of forming a germanium-antimony-tellurium material, comprising: exposing a substrate to a reactive germanium precursor and a co-reactive germanium precursor, the reactive germanium precursor and the co-reactive germanium precursor each having at least one ligand coordinated to a germanium atom, wherein the at least one ligand of the co-reactive germanium precursor is different from the at least one ligand of the reactive germanium precursor; exposing the substrate to a reactive antimony precursor and a co-reactive antimony precursor, the reactive antimony precursor and the co-reactive antimony precursor each having at least one ligand coordinated to an antimony atom, wherein the at least one ligand of the co-reactive antimony precursor is different from the at least one ligand of the reactive antimony precursor; exposing the substrate to a reactive tellurium precursor and a co-reactive tellurium precursor, the reactive tellurium precursor and the co-reactive tellurium precursor each having at least one ligand coordinated to a tellurium atom, wherein the at least one ligand of the co-reactive tellurium precursor is different from the at least one ligand of the reactive tellurium precursor; and repeating the exposing the substrate to a reactive germanium precursor and a co-reactive germanium precursor, the exposing the substrate to a reactive antimony precursor and a co-reactive antimony precursor, and the exposing the substrate to a reactive tellurium precursor and a co-reactive tellurium precursor to form a germanium-antimony-tellurium material.
