Research Interest

  • Physics and chemistry of nanostructures, application of nanotechnology to biomedical sciences, focused ion beam (FIB) technology, and surface enhanced Raman spectroscopy (SERS)

Research Overview

Dr. Yuh-Lin Wang’s research focuses on the investigation of novel nanostructures and their applications. In collaboration with Dr. Ching-Ming Wei’s group, Dr. Wang has achieved important breakthroughs in the study of self-organized surface magic-number clusters (SMCs) composed of atoms and molecules. Precise construction of nanostructures on surfaces is essential for the advancement of nanoscience and nanotechnology. SMCs are stable atomic or molecular structures that form at specific sizes on particular crystalline surfaces, enabling nanostructure arrays with atomic-scale precision. Dr. Wang’s team discovered the first SMC consisting of ten gallium atoms on the Si(111) surface, constructed the first two-dimensional SMC lattice on Si(111), and, in collaboration with Russian experimentalists, observed the first molecular SMC of C₆₀ on the Au–In(111) surface. These discoveries elucidate fundamental self-organization mechanisms and open new pathways for nanoscale design with atomic precision. Beyond atomic-scale self-organization, Dr. Wang and Dr. Juen-Kai Wang have jointly created and studied uniform arrays of plasmonic “hot spots” formed by silver nanoparticles confined within anodic aluminum oxide (AAO) nanochannels for surface-enhanced Raman spectroscopy (SERS). Self-organized AAO templates provide a versatile platform for the growth of nanoparticles and nanowires, enabling adjacent silver nanoparticles to be positioned at extremely small and uniform separations, thereby generating homogeneous plasmonic hot spots. This architecture significantly enhances the sensitivity, uniformity, and stability of SERS. Collectively, these studies contribute to establishing SERS as a reliable analytical tool for practical applications, including antibiotic susceptibility testing for patients with sepsis.
