Witryna14 sie 2024 · The impurities detected by the GC-PDHID in the aforementioned UHP N 2 samples consist of argon (Ar), oxygen (O 2), methane (CH 4), and carbon monoxide (CO). Meanwhile, hydrogen (H 2) and carbon dioxide (CO 2) cannot be seen on the chromatogram, then assumed to be lower than the PDHID's detection limit. Witryna1 kwi 2006 · The doping of HVPE GaN with O impurities increases the average positron lifetime [3].From Fig. 1 can be seen that the slope is smaller in HVPE GaN:O than in the reference sample indicating longer positron lifetime, i.e. positron trapping to vacancy-type defect. Decomposition gives one vacancy-related lifetime τ = 235 ps, which is the …
