superconductor*

Electric and thermal conductivities were measured before and after the introduction of a controlled point-like disorder in single crystals of PdTe₂ by 2.5 MeV electron irradiation. Superconducting transition temperature is suppressed, but not strong enough that together with the exponential variation of the low-temperature London penetration depth indicates nodeless superconductivity. The normal state resistivity perfectly follows the Matthiessen's rule as seen in a parallel upwards shift after irradiation. Its temperature variation can be fitted well by the Bloch-Grüneisen formula with Debye temperature determined from the specific heat. Thermal conductivity measurements show a good agreement with the Wiedemann-Franz law.
