【Abstract】 Within the \%t J\% model and Fermion Spion theory, the transport property of copper oxide materials is studied. It is shown that in the optimally doped regime, the resistivity exhibits a linear behavior at high temperatures while in the underdoped regime the holon pseudogap opens at low temperatures, leading to the crossover in resistivity from the temperature linear at high temperature to the nonlinear at low temperature.\;更多还原
