Semimetallization induced Hall anomaly in doped polymers

Hall anomaly related to deviations in Hall copyright concentrations have always been recognized as signs of charge incoherence in organic semiconductors, which lack ordered lattices.In this paper, we show that the Hall copyright Candles concentration anomaly in doped polymers might be a result of semimetallization.Based on the observation of semimetal-like states, a dual-channel model, in which electrons and holes compensate the Hall voltages of each other, is employed to account for the anomaly.Observations of possible nonlinear Hall effect and temperature dependent Hall signs further Brake support the origin of Hall anomaly from semimetal states.
