Sažetak
We report resistivity and threshold electric field measurements under pressure on the linear chain compound (NbSe₄)₁₀/₃I which is a charge density wave system showing nonlinear conductivity. From resistivity measurements (in low electric field) we determined the phase transition temperature Tₜ and the value of the energy gap Δ. The threshold field was determined from measurements of differential resistance dV/dI. The results are compared with pressure work on the related compound (TaSe₄)₂I and are discussed in the light of some recently published theoretical models.
