Scanning tunneling microscopy and spectroscopy (STM/STS) characterization of surfaces, thin films and nanostructures.
Self-assembly of functional hybrid nanostructures from combination of semiconductor, metal, semimetal and organic materials, such as organic molecule-metal nanoparticle for molecular electronics, and semiconductor-metal hybrid for photocatalysis.
Growth, STM/STS characterization and computational studies of Bi, Sb and P ultrathin films and nanostructures for novel electronic and spintronic applications.
Green Gold: Gold nanoparticles covered with PTCDA molecules. Their height and lateral size are about 2 nm and 3-5 nm, respectively. Their plasmonic resonance is strongly blueshifted so they may appear green instead of golden. Additionally, they are effective catalyst for CO conversion to CO2.
