SERS substrates by vacuum-free dealloying of Au-based metallic glass ribbons

Plasmonics has become an important photonic device due to the advancement of fabrication technologies in recent decades. It has many applications including solar cells, nonlinear optics, metamaterials, photocatalysts, and surface-enhanced Raman spectroscopy (SERS), etc. Among those, SERS

Nanostructure makes crystalline compound physically reactive

Hexagonal boron nitride (h-BN) belongs to a class of crystalline compounds with layered structure: it consists of parallel honeycomb layers, in which hexagons vertices are alternatively occupied by boron (B) and nitrogen (N) atoms. Intra-layer bonds between

Digging out self-assembly process of molecules by scanning tunneling microscopy

Molecules are known to spontaneously self – assemble into supramolecular structures in solution, on surface, and also at interface. An appropriate understanding of the process of self – assembly is of critical importance to make sophisticated nanostructures.
