Copper(II) phthalocyanine based organic electronic devices for ionizing radiation dosimetry applications

Abstract

Effects of ionizing radiation exposure of γ-rays on the copper(II) phthalocyanine thin-films are studied using photoelectron spectroscopy techniques and electrostatic force microscopy. Based on the changes observed in the electrical properties of the copper(II) phthalocyanine thin-film, organic electronic devices are demonstrated in this work for ionizing radiation dosimetry applications. Encapsulation of silicon nitride layer deposited by hot-wire CVD technique, for copper(II) phthalocyanine based organic electronic devices, has been discussed for ionizing radiation sensing. A design technique of stacking organic field effect transistors in parallel was verified for improving the current sensitivity of the sensors for ionizing radiation dosimetry.
