Nano Structures of Functional Materials

Nano Structures of Functional Materials

  • Coordinator: Prof. Satyendra Singh
  • Members: Prof. Vasundhara Singh, Prof. L.N Sharma

The main activity of the research group is the synthesis and characterization of the nanostructures of functional materials by different techniques. Recently nanostructures such as nanoparticles, nanotubes, nanowires and nanorods, of functional materials have received considerable attention from the academia and the industry due to their distinctive physical properties and potential applications in nanoscale piezoelectric transducers and actuators, ultrasonic devices, and high-density nonvolatile memory devices.
