Jing Li is a professor in the Chemistry and Chemical Biology Department whose research interests and activities are mainly in the areas of solid-state inorganic and organic-inorganic hybrid materials that possess interesting and useful properties. She will come speak about this research in the area of optoelectronics.
We have developed a unique type of inorganic-organic hybrid semiconductor materials that are made of chains or layers of binary semiconductor motifs (inorganic component) and mono- or di-amine molecules (organic component) via chemical bonds. These crystalline materials show exceptionally strong structure-, rather than size-, induced quantum confinement effect (QCE) that can be systematically tuned. They possess a number of improved/enhanced properties over their parent semiconductors including broad band-gap tenability, high absorption coefficients, improved flexibility and rich structural chemistry. In addition, they demonstrate unique and very interesting new features and phenomena that are not possible for their parent semiconductors, for example, nearly zero and tunable thermal expansion and direct white-light emission, all highly desireable for optoelectronic applications.
Pizza will be served.
