This Application Note demonstrates Raman and PL characterisation and imaging of a GaN device using an Edinburgh Instruments RMS1000 Confocal Microscope. It is shown that both optical techniques are sensitive to even the most subtle changes in the material and that when coupled to a microscope, the spatial resolution of different states within the material is possible.
