D. Nagano et al., ELECTRICAL-PROPERTIES OF SEMICONDUCTIVE NB-DOPED BATIO3 THIN-FILMS PREPARED BY METAL-ORGANIC CHEMICAL-VAPOR-DEPOSITION, Applied physics letters, 72(16), 1998, pp. 2017-2019
Epitaxially grown semiconductive Nb-doped BaTiO3 thin films with low e
lectrical resistivity similar to that of the bulk single crystal were
prepared by metal-organic chemical-vapor deposition. Thin films with 1
.5-7.5 at. % Nb content showed n-type semiconductor character. The fil
ms with 5.7 at. % Nb content showed the lowest resistivity, 2.8X10(-2)
Ohm cm. This value is three orders of magnitude lower than those repo
rted for sintered of Nb-doped BaTiO3, and similar to that of Nb-doped
BaTiO3 single crystals. (C) 1998 American Institute of Physics.
