Abstract: The current disclosure relates to a composition for depositing group 13 metal-containing material on a substrate. The composition comprises a metal alkyl precursor, wherein the metal alkyl precursor comprises a group 13 metal atom and two different alkyl ligand types. The first ligand type is a branched C4 to C8 alkyl bonded to the group 13 metal atom through a carbon atom that is bonded to three carbon atoms, and the second ligand type is a linear C1 to C4 alkyl. The group 13 metal atom is bonded to two ligands of the first ligand type, and the ratio of first ligand type to second ligand type in the composition is about two to one. Further, the disclosure relates to methods of manufacture of compositions and their uses, as well as methods of depositing material on a substrate.
