摘要:
The results of thermopower S measurements performed on implanted polyparaphenylene and polyimide films between 150 K and 450 K are presented. The implantations of Caesium or Iodine ions in polyparaphenylene with low parameters induce a sign of S characteristic to chemical nature of the implanted ions and an increase of ISI at around 350 K due to a transition from a VRH process to a polaronic conduction. With Iodine implanted sample at higher energy (E = 250 keV) and low dose (D = 2 × 1015ions/cm2) a transition from p type to n type doping at 400 K is attributed to a migration of negative oxygen ions as in the case of polyimide samples implanted with Caesium and Iodine ions where a similar behaviour of S is found.
