Variable Range Hopping Model

We report the results of the resistivity measurement on La2-xSrxCuO4 nanoparticles with x = 0, 0.05, and 0.20 evaluated by the four-point probe method. The high resistivity value shows the predominance of the inter-grain part. The temperature dependence of the conductivity can be analyzed by variable range hopping model showing the charge carriers are formed by thermal activation. There is no superconducting behavior that could be observed in La2-xSrxCuO4 nanoparticles with x = 0.05 and 0.20.

Transverse Conductivity

Temperature dependences of the electrical resistance along the c-axis of [Formula: see text] single crystals are investigated before and after irradiation with electrons at 0.5–2.5 MeV energies. The irradiation was done at [Formula: see text] K and the irradiation dose was varied from [Formula: see text] to [Formula: see text]. An enhancement of the charge carriers localization with increase of the irradiation dose has been revealed. A crossover from the pseudogap (PG) regime to the variable-range hopping conductivity has been observed.
