The above SEM photomicrograph shows columnar single crystalline structure of Ni Nano -clusters
( films) deposited on single Cu 111 zone axis to form in 3 minutes a Ni 100(Cu111) single solid phase face centered cubic (FCC ) structure from a simple watt bath of pH2 at room. As seen above, single crystal structured microscopic materials are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. A single crystal solid film is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.

The above SEM photomicrograph shows equiax cubidal polycrystalline crystal structure of Fe-MnP electrolessly deposited on Cu 111 crystal lattice zone axis . The single solid solution bcc structure of Fe20 - Mn50-P30(Fe100) alloy films was deposited from Fe, Mn phosphate and nitrate salt bath of pH2 at 50oC in 5 minutes . The inorganic phosphate co-deposited in the alloy films favors more Mn deposition than the Fe in the Fe-Mn alloy composition. The P co-deposits also influenced the formation of nano- cubidal Fe-MnP single solid solution phase structure by restricting the Fe-Mn alloy grains to nanocrystalline structure size formation.
