SUMMARY
The formation energy of a defect in semiconductors is defined as the difference in total crystal energy before and after the defect occurs. This energy quantifies the penalty associated with broken atomic bonds and lattice stress. A high formation energy indicates that the defect is unlikely to be present, as it requires significant energy to maintain. Additionally, the presence of a defect increases entropy due to the greater number of possible microstates compared to a perfect crystal.
