以噻吩为单体,在等离子体环境中聚合成致密的有机膜。利用Rutherford背散射(RB2S)和质子弹性反冲(ERD)、傅里叶红外谱(FTIR)测定了膜的成分和结构;从近红外-可见-紫外光的反射和透射谱,运用传递矩阵方法研究了膜的光学性质;此外,还探讨了24keV的I~+离子束的注入对等离子体噻吩聚合膜的掺杂效应。结果表明,注入层内电荷载流子的输运机理可用Mott的可变自由程跳跃(VRH)理论给以解释。
Thiophene as a monomer, in the plasma environment into a dense organic film. The composition and structure of the films were determined by Rutherford Backscattering (RB2S), Proton Elastic Recoil (ERD) and Fourier Transform Infrared Spectroscopy (FTIR). From the reflection and transmission spectra of NIR-visible-UV, The optical properties of the films were investigated. In addition, the doping effects of 24 keV I ~ + ion beam on the plasma thiophene polymeric films were also investigated. The results show that the transport mechanism of charge carriers in the implanted layer can be explained by Mott’s variable free-path jump (VRH) theory.
