Effect of Fe and C doping on the thermal release of helium from aluminum

The effect of Fe and C doping on the thermal release of helium from Al implanted with 10 keV, 4.0 × 10 21 ion/m 2 He at room temperature (RT) has been investigated by thermal helium desorption spectrometry (THDS) and transmission electron microscope (TEM). The results show that Fe and C doping have...

Description
Summary:The effect of Fe and C doping on the thermal release of helium from Al implanted with 10 keV, 4.0 × 10 21 ion/m 2 He at room temperature (RT) has been investigated by thermal helium desorption spectrometry (THDS) and transmission electron microscope (TEM). The results show that Fe and C doping have significant impact on the release of helium from Al and the extent depends on the doping fluence. Proper fluence of Fe and C doping would lead to the retardation of the release of helium from Al, while excessive fluence of Fe and C doping would result in more desorption peaks and the release of helium in lower temperature ranges. Fe and C doping have different influence on the release of helium from Al, and the difference is related with the secondary phases forming in the samples.
