OxidesThe ‘Oxide’ based Perovskite materials are well known for their piezoelectric, ferroeletric, dielectric properties.
Our group had carried out fundamental studies on several piezoelectric, ferroelectric, multiferroic thin films, artificial superlattice systems and nanostrcutures which enabled us to develop several technologies such as Mems for microsensors and microactuators, electron emission in microwave tube applications, very high density memory devices in nano scale and tunable microwave devices.
Currently we are embarked upon realization of emerging multicomponent oxides based epilayers and thin films for energy storage and harvesting devices and memory applications based on resistive switching in amorphous and polycrystalline perovskites.
III-NitridesThe Group III-V compound material systems which are well known for their tunable properties (as a result of alloying) has stirred the electronic industry quite a lot.
Efforts in early stages were on epitaxial GaAs based optoelectronic devices such as GaAs / Ge heterosturucture solar cells and multijunction quantum well infrared photodetectors by MOCVD.
In recent years our interest had shifted from the arsenic based III-V to eco-friendly III- nitride compound semiconductors which led to the establishment of nitride MBE Lab. Initial efforts were aimed at the basic growth optimization, fundamental understanding by extensive characterization. On going research is focused on developing quantum structures for advanced and efficient optoelectronic devices.
Emerging NanomaterialsThe increasing technological demands has pushed everyone to choose performance oriented materials without the consideration of environmental hazards.
Therefore in recent times considerable interest has been generated towards the non-toxic, environment and energy friendly materials as well as processes.
Several nanomaterial systems are proven to be effective in that direction and our group is focused on developing such technologies such as eco-friendly absorber Nanostructured materials for solar cells and 2-D materials for high performance and energy efficient devices.
