Recent Findings
Synthesis by PLD
The interfaces and strain in thin multilayers give rise to different phnomena. The materials can be engineered in form of multilayers and thin films for improving functions. We prepare functional oxide thin films and multilayers using Pulsed Laser Deposition (PLD) method.
Depending on the lattice mismatch between the substrate and the material, a compressive or a tensile strain can be induced in the strcuture which finally modifies properties of strongly correlated functional materials.
Nanoporous or nanostructured films of functional oxides can be grown using PLD in certain deposition conditions. These films can find applications as photodetectors, gas sensors, for photocatalysis, etc.
