| Abstract: | We report the observation of nonlinear conductivity with a well-defined threshold electric field ET, and frequency dependent ac conductivity, in a novel linear chain compound, (TaSe4)2I. The material undergoes a phase transition to a semiconducting phase at T ～ 260 K, and nonlinear and frequency dependent transport is observed below this temperature. We argue that the material is a new example of collective mode transport provided by a Peierls-Fröhlich charge density wave condensate. |
