摘要	Nitrogen-doped SrTiO(3) samples have been successfully prepared by nitrogen-ion implantation. X-ray photoelectron spectra clearly indicate the presence of nitrogen dopants in the crystal lattice of SrTiO(3). The ultraviolet-visible absorption spectra of nitrogen-doped SrTiO(3) show enhanced visible light absorption in the range of 400-500 nm, which contributs to the localized N 2p state in the band gap of SrTiO(3). The resistance coefficient of temperature is positive indicating metallic conducting behavior. The nonlinear dependence of voltage on current at liquid-nitrogen temperatures indicates a possible energy barrier in the grain boundary.PACS Nos.: 72.20.-i, 72.80.Ga, 78.20.-e
