Enhancement of carrier mobility in MEH-PPV film prepared under presence of electric field

Room temperature time-of-flight hole transients plot for MEH-PPV films prepared under electric field of 0V/cm, 3×103V/cm and 6×103V/cm, respectively. Electric induced polarization of MEH-PPV can significantly enhance the mobility of hole. The samples were measured under electric field of 105V/cm and excitation wavelength of 500nm.
