The stability of B atom near the Si(100)/SiO2 interface during annealing is studied by using ab initio calculation to investigate the atomic scale mechanism of B segregation at the Si(100)/SiO2 interface. Contrary to the experimental observations showing that B atoms segregate into SiO2, B atoms are found to be stable in Si free of defects. But authors can rephrase differently this sentence. On the other hand, when an O vacancy exists in SiO2, the B atom is trapped by the O vacancy and becomes quite stable in SiO2.
