Gallium nitride film on sapphire.  1um and 4 um scan

Gallium Nitride films are used for blue-light laser applications. It is important to be able to control their properties during film deposition. These films were deposited onto sapphire substrates. The hexagonal grain nanostructure is striking. They were scanned with WaveMode.
