10. The implementation of quantitative HRTEM for the GaN/InN/AIN system involves several aspects that are not outlined here but will be published elsewhere. Here, it is noted that a local strain can be separated from a local compositional change because strain distorts the geometrical dimensions of the cells in a lattice image while a compositional change affects the intensity distribution within each cell. A complete analyses allows for local stress and for local composition measurements. Sample tilt affects the pattern change and can be included in the analyses if it is small (<1 mrad).
