Anomalous depth distribution of Fe and Co atoms in polyimide implanted to high fluence.

Original language description

Polyimide foils were implanted with 40 keV Fe.sup.+./sup. and Co.sup.+./sup. ions to the flunces of 2.5 x 10.sup.16./sup. - 1.25 x 10.sup.17./sup. cm.sup.-2./sup. at ion current densities of 4, 8 and 12 .mu. A/cm.sup.2./sup. 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 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.
