Rensselaer Polytechnic Institute

Welcome to the home page of Dr. Wang’s nanoscale science world!

Dr. Wang’s group is very proud to have produced many outstanding students in the last 20 years. Eight former and current students have received over 10 national graduate student awards [e.g., AVS (American Vacuum Society), MRS (Material Research society), and PEC (Physical Electronics Conference)]. They have gone through rigorous training in science of surface, interface, and nanostructure with emphasis on hands on experimental skills, computer modeling, cross-disciplinary collaboration, technical writing and communication. Students learn how to work as team members in our group and other related research groups. They meet weekly with Dr. Wang.

All former graduates are working in the US industries or universities and make contributions to the advancement of science and technology. 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 sculptured 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, oblique angle incidence deposition, and ion sputtering. Physical properties of these nanostructures including magnetic, mechanical, electrical, transport, and structural are characterized by these surface sensitive techniques. Interested students are welcome to contact Dr. Wang.
