The relative effect of varying contents of oxygen precipitate on the impurity is also investigated. Silver proved to be a donor-type impurity in p-type silicon and its presence led to a reduction, by up to a factor of 21, in the lifetime of the minority carriers by the formation of deep level traps. While the presence of oxygen precipitate in the substrate has little or no effect on the donor-type behaviour, it improved slightly the value of the minority carrier lifetime by gettering some of the Ag impurities and there appears to be a linear dependence of the improved lifetime on the quantity of precipitated oxygen. 2023-05-13T17:49:41Z 2023-05-13T17:49:41Z 1996-07 Journal DOI: 10.1002/pssa.2211560120 https://ir.oauife.edu.ng/123456789/5500 en text/plain |
