trivacancy

plural trivacancies

1. natural sciencesA group of three vacancy defects in a crystal.

   To further investigate how the clustering of vacancies influences the mechanical properties, the most stable configurations of di- and trivacancy clusters have been predicted, which correspond to the most compact distribution of vacancies.
