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 (> 80°) 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 individual 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.
