WebThe homogeneous part can be produced, e.g., by Pt diffusion or electron irradiation, while a local sink is realized exclusively by irradiation techniques. Here, recombination-effective … Webare due to the different Pt impurity concentration and measurement temperature (70 K for #2 and 90 K for #3). Indeed, the 728 cm−1 A 1g peak shows the same peak location for sample #2 and #3 when measured at the same temperature[31]. Thus, we conclude that these three peaks originate from the platinum impurities and are not intrinsic to pure ...
