Investigation of carrier transport in the organic semiconductor 8-hydroxy-quinoline aluminium
Using the Emu spectrometer at ISIS we have recently studied charge carrier transport in the technologically important molecule 8-hydroxy-quinoline aluminium, by probing the muonated radical state via longitudinal field repolarisation. We found that at room temperature, the charge carrier motion is 1 dimensional. With an independent measure of the hyperfine coupling constant, we found the intrinsic electron mobility is 3.668x10-8 +/- 0.011 x 10-9 m^2V^-1s^-1. We also applied 2KV across the sample to assess the feasibility of measuring the electric field dependent mobilities and we found the charge carrier mobility increased to 5.44 +/- 0.25 x 10-8 m^2V^-1s^-1. This work is currently being prepared for publication. We propose to perform a full measurement of the electric field dependent mobility and finish the temperature dependence in zero electric field.
