Abstract

In this study, high refractive index polymer (HRIP) [poly(pentabromobenzyl methacrylate-co-glycidyl methacrylate)] was investigated to obtain its optical and electrical performance for optoelectronic applications. UV characteristics of the polymer in solution of tetrahydrofuran were obtained and optical band gap energy of the polymer was calculated as 3.8 eV. I-V characteristics of the polymer were investigated after HRIP thin film was prepared using spin coating technique. The electrical parameters such as barrier height I broken vertical bar(Bo), ideality factor n and reverse saturation current I-o were extracted from the forward biasing I-V characteristics. At the same time, series resistance R-s and I broken vertical bar(Bo) were determined by using a modified Norde function combined with conventional forward I-V method.
