A four-point resistivity measurement was performed on a bulk NbSe 2 I 2 single crystal, where the current was flowing in the ab-plane. Figure shows both ρ versus T and ln (ρ) versus 1/T . The resistivity of NbSe 2 I 2 increases on cooling, indicating semiconducting behavior. Noise in the resistivity measurement likely arises from the small sample size and the high resistance, near the maximum measurable for the instrument, which goes out of range below 200 K. The resistivity has a weak temperature dependence, which suggests a low activation energy, together with non-negligible intrinsic resistance from crystal defects.
