Persistent photoconductivity in strained epitaxial BiFeO3 thin films.
A drastic change in the conductivity of strained BiFeO3 (BFO) films is observed after illuminating them with above-band gap light. This has been termed as persistent photoconductivity. The enhanced conductivity decays exponentially with time. A trapping character of the sub-band levels and their subsequent gradual emptying is proposed as a possible mechanism.

15 صفحه اولThickness Dependence of Magnetic and Transport Properties of Chromium Dioxide (CrO2) Strained Epitaxial Thin Films
Chromium dioxide (CrO2) thin films of different thicknesses (120–2600 A) have been grown epitaxially on (100)-oriented TiO2 substrates by the chemical vapor deposition technique. The thicker films, with a Curie temperature of 395 K, exhibit in-plane magnetocrystalline anisotropy with the magnetic easy axis along the -axis direction. At low temperatures, the easy axis is deflected from the towar...
متن کاملEpitaxial growth of thin films
The term ‘epitaxial’ is applied to a film grown on top of the crystalline substrate in ordered fashion that atomic arrangement of the film accepts crystallographic structure of the substrate. Epitaxial growth is one of the most important techniques to fabricate various ‘state of the art’ electronic and optical devices. Modern devices require very sophisticated structure, which are composed of t...
متن کاملEpitaxial Growth of Thin Films
This chapter gives an introduction to the epitaxial growth of thin films on solid substrates. The term epitaxy refers to the growth of a crystalline layer on (epi) the surface of a crystalline substrate, where the crystallographic orientation of the substrate surface imposes a crystalline order (taxis) onto the thin film. This implies that film elements can be grown, up to a certain thickness, ...
