An Overview of Nanotechnology Research at DAV Institute of Engineering & Technology, Jalandhar

Abstract

The DA VIET Research Centre was established in January 2008 to promote research in interdisciphnary area of Nanotechnology. Universal Scanning Probe Microscope (Model NT-MDT Solver PRO M4) was imported from Russia and installed in August 2008. Hind High vac Thin Film coating unit was installed in October 2008. Thus DAVIET became the first engineering institute in North India to establish a well furnished nanotechnology laboratory. Our thurst area of research is fabrication of Quantum Dost and Nano wires for use in nanoelectronics and Opto-electronics. Template synthesis of Quantum Dots and Nanowircs has been achieved by using Anodic Alumina membranes and Polymer membranes of pore diameter varying from 20-200 nm. The electrochemical cell fabricated in our laboratory has been used to grow copper nanowires of 200 nm using an electrolyte with a composition of 20gm/100 ml CuS0₄.5H₂0 + 25% of dilute H₂SO₄ at room temperature. Using Reverse Micelle technique, nanorods of Barium carbonate and barium oxalate were synthesized along with nanocrystals of Iron oxalate. Cadmium sulphide nanocrj'stals and needles have been grown using micro-emulsion technique using different co-surfactants, (characterization of grown using micro-emulsion technique using different co-surfactants. Characterization ol"grown nanostructures has been done by using SEM, TEM and XliD.
