Through the combination and coupling of the unique properties that belong to the constituent nanomaterials, we anticipate to create new physical phenomena that can not be found previously and look forward to opening up new possibilities for the application of plasmonics. Our work will involve all four aspects of research including: (1) design of novel nanocomposite materials and devices based on well-known physical principals, (2) fabrication of novel nanocomposites, (3) characterization and analysis of the unique properties of nanocomposites, and (4) theoretical modeling of the physical properties of nanocomposite materials. The research will be focused on the following five topics: (1) Unifying mechanism of enhancement and quenching of luminescence and absorption in metal-semiconductor nanocomposites. (2) Mechanically tunable surface plasmons. (3) Searching new physical phenomena based on novel plasmonic nanocomposites. (4) Enhancement of solar cell efficiency by surface plasmons. (5) For the theoretical modeling, we will include classical simulation and quantum mechanical ab initio calculations. The work will involve the optimization of their electromagnetic finite-difference time-domain (FDTD) program for parallel-computing on their PC clusters, exploration of quantum-mechanical time-dependent density functional theoretical (TD-DFT) methods, and together with the existing ab initio electronic structure computational methods, to investigate the novel physical properties of plasmonic nanomaterials and their fascinating potential applications.電漿子學複合物半導體金屬液晶plasmonicscompositesemiconductormetalliquid crystal
