In this study induced thermally stimulated current by the TSC was measured by the open circuit method after implanting Na+ ion into a PET film. With the result, using a new theory, activated energy, escape frequency, relaxation time and ion density was evaluated.
(-) peak appeared at 363 K and 390 K when temperature increasing rate was 0.1 K/sec. and a (+) peak in the range 310~350 K. As a result of analysis, the peak at 363 K was by Na^(+) ion trapped in the surface trap and the activated energy 1. 14eV. 390 K peak had 1.66 eV activated energy and was by Na+ ion trapped in a vacance. The TSC current of 390 K peak was proportional to nuclear stopping power.
