Anomalous Depth Distribution of Fe and Co Atoms in Polyimide Implanted to High Fluence
Abstract
Polyimide foils were implanted with 40 keV Fe+ and Co+ ions to the fluences of 2.5×1016–1.25×1017 cm−2 at ion current densities of 4, 8 and 12 μA/cm2. Structural and composition alterations of the implanted polymer are studied using transmission electron microscopy and Rutherford back-scattering methods. Ion implantation results in formation of the near-surface carbonaceous layer filled up to 25 at.% of the embedded metal. Anomalous depth profiles of the metals, consisting of a strong near-surface peak and two weaker ones beyond the implanted layer, are observed. Possible mechanisms of the metal redistribution are discussed.
