Abstract :
We report on electrical and optical properties of the 1 μm thick films of conjugated polymer poly[9,9-bis-(2-ethylhexyl)-9H-fluorene-2,7-diyl] (PFO) studied by terahertz (THz) spectroscopy. The spectra of characteristics of PFO films in the 0.2-3.0 THz frequency range can be well described by Lorentz oscillator model.
