Research Areas:
Examples of research areas are non-equilibrium growth and etching of metal and semiconductor films, magnetism of ultrathin magnetic films and dots, transport properties of metallic and magnetic films and nanotubes, fabrication and growth mechanism of sculpture films. The lab has been equipped with state of the art commercial and homemade techniques for fabrication and characterization of novel nanostructures. Examples of real space and diffraction techniques are scanning tunneling microscopy (STM), atomic force microscopy (AFM), nanolithography, high resolution low energy electron diffraction (HRLEED), energy filtered reflection high energy electron diffraction (EFRHEED), angle resolved light scattering (ARLS), Auger electron spectroscopy (AES), x-ray photoelectron spectroscopy (XPS), four point probe, magneto optic Kerr effect (MOKE), magnetoresistance, and ferromagnetic resonance. Examples of growth/etching techniques include thermal evaporation, chemical vapor deposition, atomic layer deposition, glazing angle incidence deposition, and ion sputtering.
