摘要:

I have broad experience in developing organic and inorganic (III-V and II-IV nanocrystals) materials with novel photophysical and electronic properties, particularly in various aspects of materials design, synthesis, characterization and testing in devices. I have been the principal investigator in various research projects to create new materials for optoelectronic devices. Specific topics included organometallic phosphorescent materials, organic electron and hole transporting materials, and II-VI and III-V compound semiconductor nanocrystals for light-emitting diode and phosphor applications for solid state lighting. Over the years, I’ve also developed expertise in understanding of the photophysical processes and the mechanism of charge generation/migration/recombination in organic/inorganic materials, and in structure design and optimization of optoelectronic and related devices.  I am foremost an experimentalist with 12 years of laboratory exp erience in semiconductor materials and devices. I enjoy learning and developing new material systems, processes, and characterization methods. I have successfully demonstrated novel materials by innovating new designs and processes at both the academic and industrial level. I have developed many new ideas that have resulted in various patents and new products.
