Description
We have grown transition metal (Fe, Mn) doped GaN thin films on c-oriented sapphire by metal-organic chemical vapor deposition. By varying the flow of the metal precursor, a series of samples with different ion concentrations are synthesized. Microstructural properties are characterized by using a high-resolution transmission electron microscope. For Fe over-doped GaN samples, hexagonal Fe 3N clusters are observed with Fe 3N(0002) parallel to GaN (0002) while for Mn over-doped GaN, hexagonal Mn...[Show more]
