Abstract
The secondary ion yields of polytetrafluoroethylene (PTFE) and polyethylene (PE) were compared with that of Al+ emitted from Al2O3 using mixed samples of their powders. The surface compositions of mixtures were measured by means of X-ray photoemission spectroscopy (XPS). Secondary ion mass spectrometry (SIMS) measurements with 1 keV Ar+ showed that the secondary ion yields of CF+ from PTFE and C2H+3 from PE were ∼ 20 and ∼ 4 times larger than that of Al+ from Al2O3, respectively. The sputtering yield of PTFE was also examined by weight loss measurements; the results suggest that the large secondary ion yield of PTFE is primarily due to its large sputtering yield.
