Influence of substrate on structural and transport properties of LaNiO3 thin films prepared by pulsed laser deposition

Abstract

We report the structural and transport properties of LaNiO 3 thin films prepared by pulsed laser deposition technique. To understand the effects of film thickness, lattice mismatch and grain size on transport properties, various oriented substrates were used for deposition, including single-crystalline SrLaAlO 4 (001), SrTiO 3 (100) and LaAlO 3 (100). To achieve a high quality LaNiO 3 thin films, the vital parameters (such as laser fluence, substrate temperature, oxygen pressure, and deposition time) were optimized. The best quality films are found to be well textured samples with good crystalline properties.

Comparative study on magnetoresistance of carbon-cobalt nanocomposite thin films grown by pulsed laser deposition

“…In this paper we present our latest results on magneto-transport properties of C 1−x Co x thin films (with 0.1 < x < 0.2) grown by the Pulsed Laser Deposition (PLD) technique. [26][27][28][29][30][31] Some interesting features in the magnetic field and doping dependences of the measured magnetoresistance have been observed and their origin has been discussed in detail using the up-to-date transport scenarios.…”

Kaolinite Thin Films Grown by Pulsed Laser Deposition and Matrix Assisted Pulsed Laser Evaporation

“…The experimental set-up of the PLD system is simple and versatile with great development potential and compatibility for a wide variation of oxides and hydroxides. By using pulsed lasers and a vacuum chamber, a variety of stoichiometric oxide films can be grown in vacuum, reactive or inert background gas without the need for further processing [ 15 ]. Based on the vast applications (i.e., biotechnology, microelectronics, optoelectronics) that are relying on these oxides and hydroxides, an increasing research interest was observed regarding PLD technique in the processing of these materials.…”
