M. Kamei et al., HETEROEPITAXIAL GROWTH OF TIN-DOPED INDIUM OXIDE-FILMS ON SINGLE-CRYSTALLINE YTTRIA-STABILIZED ZIRCONIA SUBSTRATES, Applied physics letters, 64(20), 1994, pp. 2712-2714
Heteroepitaxial growth of tin-doped indium oxide (ITO) film was achiev
ed for the first time by using single crystalline yttria stabilized zi
rconia (YSZ) as substrates. The epitaxial relationship between ITO fil
m and YSZ substrate was ITO[100] parallel-to YSZ[100]. By comparing th
e electrical properties of this epitaxial ITO film with that of a rand
omly oriented polycrystalline ITO film grown on a glass substrate, nei
ther the large angle grain boundaries nor the crystalline orientation
were revealed to be dominant in determining the carrier mobility in IT
O films.
