How to calculate Etch pitch density from Atomic Force Microscope (AFM) images for GaN-based material?

05 April 2018 1 818 Report

Dear Researchers,

I have etched GaN based material. I have taken the Atomic Force Microscope (AFM) image. How do I calculate Etch pitch density from the AFM image?

Thank you

Raul D. Rodriguez

Most AFM and scanning microscopy software have a function for particle analysis. You could also use that to quickly quantify the pitch density.
