Nanostructures such as nanorods, nanowires and nanosprings are building blocks of future nanomachines and have potential applications in nanosensors and nanodevices. However, the controlled synthesis of nanostructures and the measurements of magnetic, mechanical and electrical properties of an individual nanostruture are challenging. One of the methods to grow these nanostructures is glancing angle deposition (GLAD) technique, which is relatively straightforward and allows a single step fabrication of nanorods and other desired geometry. This is a physical vapor deposition in which flux arrives at a large oblique incidence angle(> 80o) from the substrate normal while the substrate is rotating. This results in the formation of isolated nanorods by the self-shadowing mechanisms. We are developing a ultra-high vacuum GLAD nanostructures deposition system attached with a scanning tunneling microscope (STM) to study the electrical, thermal, mechanical and electromechanical properties of indvidual nanostructures. This will allow us a single step fabrication of nanostructures and their insitu characterization.  Interested students are welcome to contact me for Ph.D. 

           J.P. Singh received his PhD in the field of scanning probe microscopic studies of ion beam irradiated semiconducting surface in 2002 from Inter University Accelerator Centre, New Delhi (Jawaharlal Nehru University, New Delhi). He was at Rensselaer Polytechnic Institute, NY working on the field of applications of glancing angle deposited sculptured thin films for about 3 and half years. He joined Department of Physics at IIT Delhi in 2005. His current research includes photomechanical properties of carbon nanotubes, glancing angle deposition, optical and mechanical properties of metal oxides, nanomechanical properties of nanorods and nanospring structures, and nanofluidics.
