Abstract

Zn_0.3In_1.4Sn_0.3O_3-δ (ZITO) thin films were grown by computer-controlled pulsed laser deposition (PLD) on (0 0 0 1) Al₂O₃ substrate. Cross-section and plan-view transmission electron microscopy (TEM) revealed that the ZITO films were composed of twin-related domains with their (2 2 2) planes parallel to (0 0 0 1) planes of the Al₂O₃ substrate. ZITO {5 over(5, -) 0} planes fitted well to Al₂O₃{3 over(3, -) 0 0} planes with a lattice mismatch of approximately 2.8%. Remarkable enhancement of electrical conductivity, about one order of magnitude higher than that of bulk ZITO, was found. The formation of twin-related domains and its effects on electrical and optical properties of ZITO films were also discussed.
