Are vacancies supposed to form clusters?

12 December 2018 0 10K Report

here are monochromatic cathodoluminescence images and rg composite image of BaTiO3 my question is are vacancies supposed to form a cluster? thermodynamically? cuz I think vacancies are randomly distributed that it sounds reasonable that two types of vacancies are located at close sites thank you

Is doping in BaTiO3 only related to prevent oxygen vacancy migration?

I am wondering the reason for doping in BaTiO3 dielectric I know it helps with Vo migration to cathode in MLCC I wonder if there are any other reasons for doping. can anyone answer? thank you
