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).

Research Focus

Thin Films and Nanowires

The focus of this research effort is to synthesize and characterize tunneling magneto resistance (TMR) materials in a form of nanowires vertically standing and substrate supported. This is achieved by filling the cylindrical empty interior space in carbon nanotubes and also by constructing nanocolumns through glancing angle deposition. The properties are compared with that of thin films synthesized under similar conditions. TMR materials with high enough MR ratio at room temperature can be used for several applications including sensors, logic gates, and MRAM in quantum computers. Nanowires / nanocolumns form makes it applicable for components in NEMS (nano-electromechanical systems).
