Research Abstract

As novel evaluation tools for the organic devices, time-resolved microscopic SHG and charge modulated spectroscopy measurements are developed for imaging the electric field and carrier distribution. Effect of carrier traps on transient carrier transport was studied from experimentally and theoretically. Further complementary study of the electric field and carrier distribution was performed to discuss the mobility distribution.
