CDW phase transition driven by electrical pulse. (a) The phase transition can be driven by electrical pulse. As an electrical pulse travels through the sample, the melting of C phase occurs to generate highly conductive hidden states. (b) Temporal response of 1T-TaS₂ by applying a current pulse. (c) The pulsed V–I characteristic at different temperatures. (d) The temperature-dependent V₀ and I_T. V₀ is the voltage at I = 0 mA and I_T is the threshold current for the phase transition.
