英文摘要	We demonstrate the potential of electrons for single molecule diffraction and imaging using C-60 molecules confined inside single-walled carbon nanotubes (C(60)s@SWCNT or peapod) as a model system. A 25 nm diameter electron beam from a field emission gun source is used to record diffraction patterns from individual peapods using imaging plates. The electron beam illuminates about 25 C-60 molecules. Experimentally, we found that the molecules diffract inside similar to 15% of the host nanotubes. With the help of simulations, we explore the limits of electron molecular diffraction and its sensitivity to the molecular configurations. We show that the combination of electron diffraction and electron direct imaging provides the best approach to single molecule imaging. (C) 2011 Elsevier B.V.
