Protective-layer-coated single-walled carbon nanotubes (SWNTs) with palladium nanoparticle decoration (Pd-SiO2-SWNTs) were fabricated and their sensing properties for hydrogen (H-2) were investigated. SWNTs were coated with a 3-4 nm thick SiO2 lay...
We fabricated a highly stable and sensitive gas sensor based on single-walled carbon nanotubes (SWNTs) protected by metal-oxide coating layer. SWNTs were deliberately decorated with 2-5 nm of oxygen-deficient SiO(x) and AlO(x) by pulsed laser depo...
The density of states (DOS) of single-walled carbon nanotubes (SWNTs) grown on a metal tip apex was investigated by scanning tunneling spectroscopy (STS). SWNTs were synthesized directly on a Ptlr tip by thermal chemical vapor deposition and utili...
The facet surface of a Ge nanocrystal prepared on Si(111) was investigated by scanning tunneling microscopy and spectroscopy (STM/STS) using a metal-coated carbon nanotube tip. Because of the small radius and high aspect ratio of the tip, we obser...
The solid-phase epitaxial growth process and surface structure of MnSi oil Si(1 1 1) were investigated by coaxial impact-collision ion scattering spectroscopy (CAICISS) and atomic force microscopy (AFM). For the Si(1 1 1) sample deposited with 30 ...
