We focus our research on the properties of nanomaterials and their applications to optoelectronic devices and biomedicine; especially, taking advantage of nanomaterials to enhance the performance of optoelectronic devices and to develop the target drugs for cancers. Scanning probe microscope, optical spectrometer, X-ray photo-electron spectrometer and impedance analyzer are the major analytical tools in our study. Undertaking those researches, the engaged students can establish their capabilities in stand-alone working, work plan sketch, trouble shooting and self-expression.
