DEFECT INDUCED NOVEL ELECTRICAL, MAGNETIC AND OPTICAL PROPERTIES OF TIO2 THIN FILMS GROWN BY PULSED LASER DEPOSITION

Abstract

For over half a century, rutile TiO2 has been intensively studied by experimentalist and theoretical scientists due to its interesting physical properties, such as high static dielectric constant and large uniaxial refractive index. However, over the last few decades, anatase TiO2 has become the heart of research due to its better electrical properties which make it more suitable over rutile phase for solar photovoltaic, photo catalytic, transparent conductor (TCO), dilute magnetic semiconductor applications. The objective of this thesis is to investigate the defect induced electrical, optical, magnetic and structural properties of titanium dioxide (TiO2) thin films grown by pulsed laser deposition (PLD) technique.
