<div dir="ltr"><div>This isn't really a quantum espresso specific question, but are you looking for the formation energy of a vacancy defect? Computing that with DFT is well documented, there is an archive paper that discusses that: <a href="https://arxiv.org/abs/1906.06609" target="_blank">https://arxiv.org/abs/1906.06609</a>.
