a, Electric field profile of the GaN/Al0.81In0.19N (LM-AlInN) sample along the \(\left[ {1{\bar{1}}{{{\mathrm{00}}}}} \right]\) zone axis by tDPC STEM (blue cross mark) and fitting result based on the Fang-Howard wave function using the Markov chain Monte Carlo optimization (orange line). b, Electric field profile of the GaN/Al0.88In0.12N (PM-AlInN) sample along the \(\left[ {1{\bar{1}}{{{\mathrm{00}}}}} \right]\) zone axis by tDPC STEM (blue crosses) and fitting result based on the same method (orange line).
