3A02 液晶性有機半導体における不純物ドーピングによるキャリア移動度への影響(物理・物性)

抄録

We have investigated the effect of impurity doping in a 2-phenylnaphthalene derivative on its charge carrier transport. We found that the ionic current observed in SmA, which depended on the light intensity. We discuss how we can estimate the concentration of the impurities in the liquid crystals from the transient photocurrents.
