Dear Physics Forum(adsbygoogle = window.adsbygoogle || []).push({});

It has been reported that the lattice mismatch of GaN/Sapphire is ~13.9%.

I have tried the following formula, but got the wrong answer:

[(GaN-Al2O3)/GaN] x 100%

where:

GaN = 3.189 Angstroms

Al2O3 = 4.765 Angstroms

Obviously I am missing something huge.

Thank you.
