Organic materials present a potential source for high-performance, low cost electronics and photonics but there has been a barrier to their use in the difficulty of understanding their charge transport properties because of their disordered nature and the coexistence of several transport mechanism. In my presentation I go over the various techniques and challenges to attempt to measure the transport mechanism of a specially prepared organic material of conjugated polymer brushes. In it I will describe the geometry of films of conjugated polymer brushes in addition to potential problems in the measurement process as a result of the chosen geometry and the inherent properties of polymer brushes. Then I will describe the steps of measurements of I-V and C-V responses of the brushes to different biases in the time-independent and time-dependent regimes and how they can reveal properties of charge injection, transport and relaxation in the brushes.
