摘要：

A band mechanism for transport in single-crystal strontium titanate (STO) is used as a basis for estimating the parameters characterizing the localization and redistribution of space charge in STO for T<100 K. A comparison of the experimental and calculated temperature dependences of the charge carrier concentration yield an estimate for the location of the Fermi level in STO at T=4.2 K with E-F-F-v similar to 10 meV. The phenomena at metal/STO and YBCO/STO contacts are discussed. (C) 1997 American Institute of Physics.
