  abstract = {Complex impedance and conductivity were measured for regioregular
	poly(3-hexylthiophene) (P3HT) at alternating current (AC) voltages
	using a waveform technique. The waveforms were Fourier transformed
	from time domain to frequency domain and analyzed at fundamental
	and higher order harmonic frequencies. It was found that the impedance
	of the semi-conducting P3HT decreases with increasing electric field
	strength. The non-linear charge transport is dominated by a third
	harmonic response that originates from extended polarizability of
	p-type electronic states. The third order non-linear conductivity
	can be used to quantify the effect of an electric field on the conduction
	mechanism and to correlate the intrinsic charge carriers mobility
	with molecular structure},
