Abstract: The current disclosure relates to vapor phase methods of depositing a metal or a semimetal-comprising materials on a substrate. In the methods, various metal or semimetal precursors may be used together with reactants that may generate hydrogen radical or amino radical to react with the metal or semimetal precursor to deposit the metal or semimetal-comprising material on the substrate. The disclosure further relates to materials and structures deposited by the disclosed methods, as well as deposition assemblies.
