M. Pekala et al., THERMOELECTRIC-POWER AND THERMAL-CONDUCTIVITY OF NEUTRON-IRRADIATED SUPERCONDUCTORS YBA2CU4O8, Physica status solidi. b, Basic research, 186(2), 1994, pp. 487-492
The first thermoelectric investigation of fast neutron irradiated poly
crystalline superconductors YBa2Cu4O8 reveals that with a rising fluen
ce the absolute values of thermoelectric power increase gradually, the
transition temperature shifts from 77 to 72 K, whereas the thermal co
nductivity diminishes due to the suppression of electron and phonon me
an free paths by the defects created in the CuO2 layers.
