Nanoscratch Characterization of GaN Epilayers on c- and a-Axis Sapphire Substrates

<p>Abstract</p> <p>In this study, we used metal organic chemical vapor deposition to form gallium nitride (GaN) epilayers on c- and a-axis sapphire substrates and then used the nanoscratch technique and atomic force microscopy (AFM) to determine the nanotribological behavior and de...
