In addition to this, the department has laboratory facilities to carry out research in Molecular Spectroscopy, Solar Energy, Thin Film Physics, Thin Film Solar Cell, Solid State Ionics, Crystal Growth etc. The facilities include FTIR spectrophotometer, UV-Vis spectrophotometer, Atomic Absorption spectrophotometer, Vacuum coating Unit, Solar energy measuring instruments, and other basic facilities.
Thermal Evaporation is one of the simplest of the Physical Vapor Deposition (PVD) techniques. The thermal evaporation of materials in vacuum is a versatile and popular method to provide a thin film coating on a substrate. In evaporation a material is heated in vacuum until it boils, the resulting vapour then condenses on the substrate to form a thin film. This film can be from a few atoms thick (less than 1nm) to hundreds or thousands of nm thick. Thermal evaporation is carried out at high vacuum, typically better than 1×10-6 mbar.
For materials with higher melting points which cannot be easily evaporated by resistive heating the e-beam evaporation processes are used. Resistance evaporation systems pass a high electrical current through a filament or a ‘boat’ source in which the material is placed, the heating effect of which is sufficient to evaporate many materials. Electron beam sources use a dedicated power supply to provide a high-power electron beam to heat the source material, and are capable of evaporating higher melting point or reactive materials.
Further specialized sources with closed-loop temperature control are available for applications such as the evaporation of organic materials for OLED displays.
The Department Library occupies a unique place in academic and research activities of the Department. It is perhaps the most important central facility provided by the Institute. These books include collection of prescribed textbooks for UG / PG level teaching and a collection of few advanced research level books.
