Table 1
Summary of the calculated trap properties for both investigated deposition series and for samples with and without PDT. In all cases, different evaluation methods have been used to determine the trap properties (manual maximum analysis and DLTFS evaluations). Therefore an average and standard deviation is given for each variation and each trap.
