| 摘 要： | Strontium titanate (SrTiO3) has been widely used as substrates for growing perovskite oxides thin films be- cause SrTiO3 is chemically and compositionally stable, and has small lattice mismatch with many perovskite oxides1―3]. It is known that SrTiO3 it…

| Abstract: | The studies on structure and electrical characteristic of Nb-doped SrTiO3 (SNTO) substrates by XRD, Hall measurements, R-T and SEM, show that the SNTO substrates with the same Nb-doping concentration have different electrical properties be- cause of the nonuniformity of Nb-doping. The uni- formly doped high-quality substrates are extremely important for fabricating multilayer structure and de- vices. In addition, the experimental results also pro- vide us with SEM method to judge the uniformity of conducting material. |
