Electronic Materials and Devices
The Division of Electronic Materials has undertaken R & D work on several types of materials :
electroluminescent, photovoltaic and electrochromic materials, nanostructured materials, high temperature superconducting materials, advanced ceramic materials and polymeric materials, Efforts have also been made to develop devices involving these materials, in thin and thick film form as well as in bulk form, with the objective of transferring successfully developed technologies to industry. Besides, the study and characterization of surfaces and nanostructures is a major activity in this division. The division includes the following groups :
Luminescent Materials and Devices Group
Development of phosphors/nanophosphors by different synthesis routes for applications in several display devices. New down-conversion phosphors/nanophosphors for solid state lighting in conjunction with blue/ near UV LED. Synthesis of doped ZnO nanophosphor through different precursor routes to obtain p-type conductivity.
Plasma Processed Materials, Devices and Systems Group
R & D on amorphous and micro/nano silicon, and carbon, based thin films, devices and systems. Ongoing work on diamond-like carbon films. Tetrahedral amorphous carbon films deposited by filtered cathodic vacuum arc technique.
