Sumario:SrTiO(3) is a model of the perovskite-like compounds for structural transition which inducing the intriguing physical properties around the critical phase transition temperature T(AFD) (antiferrodistortive, abbrev. as AFD). Here we report that the electrical transport behavior is a new way to quantify Nb concentration for Nb-doped SrTiO(3). The lattice parameter (c), phase transition temperature (T(AFD)), and the carrier concentration (n) of SrTiO(3) may be manipulated by niobium doping. T(AFD) increases with increasing the niobium content in a rate of about 30 K per (wt%, i.e. niobium element’s weight verses total weight) niobium and n in a rate of about 2.5 [Formula: see text] 10(20)/cm(3) per (wt%) niobium.
