Structural and electro-optic properties of pulsed laser deposited Bi4Ti3O12 thin films on MgO
نویسنده
چکیده
Ferroelectric Bi4Ti3012 thin films have been grown on MgO ( 100) and MgO( 110) substrates by the pulsed laser deposition. X-ray diffraction studies show that the films on both substrates have preferential crystallographic orientation such that most of their c axes are close to the substrate normal direction. The film on MgO( 110) shows quadratic and hysteretic electro-optic characteristics with the effective coefficient of about 3.8~ lo-*’ m*/V’.

Pulsed laser deposition of BaTiO3 thin films and their optical properties
Highly oriented a-axis BaTiO3 thin films were grown by pulsed laser deposition on ~001! MgO substrates. The full width at half-maximum of the ~200! BaTiO3 rocking curve was as narrow as 0.6°. A large hysteretic quadratic electro-optic effect was observed in a transverse geometry at 6328 Å. A birefringence shift up to 3310 was measured at an applied dc electric field of 1 kV/mm. It was found tha...

This thesis deals with the microstructure effects on the optical properties of (i) polycrystalline Nd-modified lead-zirkonium-titanate (PNZT) and (ii) highly oriented BaTiO3 (BTO) thin films together with the stacking structure influence on the optical properties of (iii) BaTiO3SrTiO3 (STO) superlattice thin films. All the films were grown on MgO(001) substrates by pulsed laser deposition. Dif...
متن کاملInterface control by homoepitaxial growth in pulsed laser deposited iron chalcogenide thin films
Thin film growth of iron chalcogenides by pulsed laser deposition (PLD) is still a delicate issue in terms of simultaneous control of stoichiometry, texture, substrate/film interface properties, and superconducting properties. The high volatility of the constituents sharply limits optimal deposition temperatures to a narrow window and mainly challenges reproducibility for vacuum based methods. ...
متن کاملOrientation of MgO thin films on Si(001) prepared by pulsed laser deposition
Pulsed laser deposition method was employed to grow MgO thin films with preferred orientation on bare Si(100) and SiO2/Si(100) substrates. The orientation of MgO thin films was systematically investigated by varying deposition parameters. XRD analysis showed that the preferred orientation of MgO thin films would change from (111) to (100) when laser fluence decreased and oxygen pressure increas...
