The Seifu Research Group (SRG)

Research Interests: Nanoscience and Nanotechnology.

The research at the nanoscience and nanotechnology laboratory is directed at understanding:

  • magnetostrictive materials with the goal of developing in situ sensing of damages in various polymer composites;
  • magnetic nanocomposites' enhanced magnetic properties via ferromagnetic proximity induced ferromagnetism in carbonaceous matter with the goal of developing nano-sensors; and
  • multi-layered thin films to tunneling magneto-resistance (TMR) materials in the form of nanowires synthesized by filling vertical standing and substrate supported nanotubes and also by constructing nano-columns through glancing angle deposition. TMR materials with a high enough MR ratio at room temperature can be used for several applications that include sensors, logic gates, and MRAM for quantum computers. TMR in nanowires / nano-columns form is applicable for components in NEMS (nano-electromechanical systems).
