In this talk we report the results of theoretical calculations for the
electronic structure and the quantum transport of nanoscale devices
utilizing carbon nanotubes. Especially, we study the effect of vacancies
such as single and double vacancies on the electrical properties, whose
structures are fully optimized by reconstruction, and examine the
electrical conductance of carbon nanotubes with multiple vacancies,
which are randomly distributed. We also discuss the effect of interwall
interactions on the transport properties of double-wall, multiwall, and
telescoping carbon nanotubes, based on first-principles and tightbinding calculations and the spectral statistics.
