  • Profile

    Dr. Shen is an Associate Professor in the Department of Electrical Engineering. Before joining CCNY, he worked at Nortel Networks (Ottawa, Canada), National Research Council (Ottawa, Canada), Tohoku University (Sendai, Japan), Laboratoire de spectrométrie physique (Grenoble, France), and Fraunhofer Institute for Applied Solid State Physics (Freiburg, Germany).

    Dr. Shen's research is focused on the growth of various compound semiconductor materials by molecular beam epitaxy (MBE). He pioneered the research on III-V ferromagnetic semiconductors. Very recently, he established the new capability at CCNY to grow ZnO-based wide band gap semiconductors. In addition to study various physical properties of MBE-grown nano-materials and nano-structures, his research group is also investigating numerous device applications. Dr. Shen has published more than 100 peer-reviewed articles plus 150 conference and meeting presentations. His journal publications have been cited for more than 3000 times according to ISI's Web of Science.

    Dr. Shen is a member of the American Physical Society, the American Vacuum Society, and American Association for the Advancement of Science. He is a Program Committee member of the 15th International Conference on II-VI Compounds, a Program Committee member of the 1st MIRTHE-IROn-SensorCAT Virtual Conference, and the editor of the 26th North American Molecular Beam Epitaxy Conference.
