Nanotube Peapods Friday, February 1, 2002 Scientists recently discovered that nanoscopic peapods — the latest class of nanomaterials created by filling the cores of single-wall nanotubes – have tunable electronic properties. Our measurements show that encapsulation of molecules can dramatically modify the electronic properties of single-wall nanotubes. We also show that an ordered array of encapsulated molecules can be used to engineer electron motion inside nanotubes in a predictable way. By mapping electron waves of different energies inside these nanoscale structures, we can begin to unravel the complex interaction in these systems, and better understand their electronic properties. “Mapping the One-Dimensional Electronic States of Nanotube Peapod Structures,” D. J. Hornbaker, S-J Kahng, S. Misra, B. W. Smith, A. T. Johnson, E. J. Mele, D. E. Luzzi, and A. Yazdani, Science 295, p 828-831, (2002).
