Abstract

Electrical-transport measurements are reported on high-purity H₂(pc)I single crystals and their alloys with Ni(pc)I in the temperature range from room temperature to 20 mK and in magnetic fields up to 5.5 T. We have observed a sharp maximum in conductivity at 1.8 K which we attribute to crossover from one- to three-dimensional behavior. The conductivity follows a simple quadratic temperature dependence below 1.8 K and remains metallic (≈ 10⁴ Ω^-1Cm^-1) at very low temperatures. A negative contribution to the magnetoresistance appears at 1.8 K consistent with weak-localization theory.
