Biography

Born in China, Feng obtained a doctoral degree in Physics from the Australian LaTrobe University in 2000. Since 2003, Feng has been working at the Department of Physics of the University of Puerto Rico, Rio Piedras Campus (UPRRP) where he develops plasma processing of multifunctional nanomaterial laboratory. The main focus of his research is on nanostructured materials using especial materialsdesign concepts. The rationale for the research of nanostructured materials is based on the fact that logical properties change drastically as the structures of the film reduces to the nanoscale. The emphases of his research are on mutilfunctional properties including optoelectronic, magnetoelectric, optomagnetic response, and gas- or photon -sensitivity, as well as the ir applications on sensor, solar cells, and electronic devices with long-term performance, reliability, and cost-effectiveness. The research projects involve both graduate and undergraduate students of Physics, Chemistry and Chemical Physics. The research projects are sponsored by Institutional Research Fund of UPRRP, PR-EPSCoR, the United States Department of Defense, and the National Science Foundation. These projects are moving into the testbed phase through the Institute for Functional Nanomaterials (IFN).
