WebN2 - We investigated how selective wet etching changes the surface morphologies of nonpolar a-plane (11 2 0) and semipolar (11 2 2) GaN films grown on sapphire substrates. Trigonal prisms with various widths are seen on the top surface and the tapered sidewall facet of the a-plane GaN films along the c-axis direction. WebThe silicon sidewall of a 4-μm-deep waveguide structure etched by this method has a root mean square roughness below 10 nm and a peak-to-valley (P-V) roughness below 60 nm. …
