Researches in Saito Laboratory

Outline of the Research We are studying on nano-scaled materials (such as carbon nanotubes etc.) and surface and interface (low-dimensional) structure of semi-conductors and metals. Transmission electron microscopy (TEM), scanning tunneling microscopy (STM), reflection high-energy electron diffraction (RHEED), X-ray diffraction (XRD), synchrotron radiation (SR) are our main tools. In addition to reveal a new physics on such materials, applications of nano materials to electronic devices are also studied.
