Abstract
The incorporation of selected impurities in Si grain boundaries is investigated using specialized analytical techniques. Specifically, H-diffusion, Al-diffusion and As-segregation mechanisms are studied, and the direct chemical mapping of these impurities on grain boundary planes is presented for the first time. These analyses utilize Volume-Indexed SIMS and AES for the identification of the impurity species, the concentrations and the exact spatial location. The passivation of the intergrain regions by these impurities is discussed.
