WitrynaImpurities with larger differences in valence from the host typically produce states which are much further from the band edges – called deep levels. These take more thermal energy to release carriers, so are less important in determining carrier concentrations. However, they can trap free carriers and allow them to interact with carriers Witrynaspreadsheet) of the data is recommended. Impurities should be designated by code number or by an appropriate descriptor, e.g., retention time. If a higher reporting threshold is proposed, it should be fully justified. All impurities at a level greater than (>) the reporting threshold should be summed and reported as total impurities.
