A Study of ZnO Buffer Layer Effect on Physical Properties of ITO Thin Films Deposited on Different Substrates
The improvement of the physical properties of Indium Tin Oxide (ITO) layers is quite advantageous in photovoltaic applications. In this study the ITO film is deposited by RF sputtering onto p-type crystalline silicon (c-Si) with (100) orientation, multicrystalline silicon (mc-Si), and glass substrates coated with ZnO and annealed in vacuum furnace at 400°C. Electrical, optical, structural a...
متن کاملOrientation-tuning in self-assembled heterostructures induced by a buffer layer.
Anisotropic nano-plate structures in self-assembled perovskite-spinel thin films, BiFeO3-NiFe2O4 and BiFeO3-CoFe2O4, which were deposited on (001)c SrRuO3/SrTiO3 and DyScO3 substrates, respectively, have been demonstrated using transmission electron microscopy combined with strain analysis. Unlike the unitary cube-on-cube orientation relationship reported widely, the growth direction of the CoF...
متن کاملDepth resolved lattice-charge coupling in epitaxial BiFeO3 thin film
For epitaxial films, a critical thickness (tc) can create a phenomenological interface between a strained bottom layer and a relaxed top layer. Here, we present an experimental report of how the tc in BiFeO3 thin films acts as a boundary to determine the crystalline phase, ferroelectricity, and piezoelectricity in 60 nm thick BiFeO3/SrRuO3/SrTiO3 substrate. We found larger Fe cation displacemen...
متن کاملEffect of substrate orientation on lattice relaxation of epitaxial BiFeO3 thin films
We have investigated detailed structural properties of epitaxial BiFeO3 thin films grown on 001 , 110 , and 111 SrTiO3 substrates in thicknesses up to 1 m. X-ray reciprocal space mappings reveal that the fabricated films have crystal structures and the strain relaxation dictated by the substrate orientation. The rhombohedral structure, which is observed in the bulk form, is maintained only when...
متن کاملStrained relaxation in buried SrRuO3 layer in (Ca1-xSrx) (Zr1-xRux)O3/SrRuO3/SrTiO3 System
A novel relaxation phenomenon occurs in buried SrRuO3 layers in strained (Ca1-xSrx) (Zr1-xRux)O3/SrRuO3/SrTiO3 (001) thin film system. The lightly strained SrRuO3 buried layer is initially clamped by the SrTiO3 substrate. After a heavily strained (Ca1-xSrx) (Zr1-xRux)O3 overlayer is deposited, localized strain relaxation develops in the buried layer. This is manifested by a crosshatch pattern o...
