This paper demonstrates that combining mid-infrared and terahertz scattering-type scanning near-field optical microscopy (s-SNOM) enables high-resolution, non-destructive characterization of homo-epitaxial GaN p-i-n diodes by successfully disentangling carrier and lattice properties and detecting sub-surface defects with superior sensitivity compared to traditional metrologies like micro-Raman and KPFM.
