摘要：
The results of an experimental study of the resistivity rho and thermopower in the temperature range 4.2 - 300 K are presented for commercial-grade copper subjected to plastic deformation at room temperature. A number of inter-correlated anomalies, due to dislocations, are observed in the temperature dependence of the resistivity and thermopower. The probable cause of these anomalies is the resonance scattering of free electrons and thermal phonons by electrons localized near the dislocations. (C) 2005 American Institute of Physics.
