Research Interests

My group is about Spintronics in π-conjugated organic semiconductor. We fabricate various organic spintronics devices such as organic spin valves, organic light emitting diodes (OLEDs), organic solar cells, spin-OLEDs and perform optical and magneto-electrical characterization of those devices. We optimize the device performance by investigating carrier-spin related interaction such as hyperfine interaction and spin-orbit interaction in the organic semiconductor. We possess various optical experiments to characterize the π-conjugated semiconductor thin films and devices such as photocurrent, photo- and electro-luminescence, photo- and charge-induced absorption.
