Conductance through atomic contacts created by scanning tunneling microscopy
(Elsevier, 1999)We investigate conductance through contacts created by pressing a hard tip, as used in scanning tunneling microscopy, against substrates. Two different substrates are considered, one a normal metal (Cu) and another a ... -
A First-principles Study of the Structure and Dynamics of C8H8, Si8H8, and Ge8H8 Molecules
(American Chemical Society, 2000)We present a first-principles study to elucidate the nature of the bonding, stability, energetics, and dynamics of individual X8H8 molecules (X = C, Si, Ge). The results obtained from both "local basis" and "pseudopotential" ... -
Pressure-induced interlinking of carbon nanotubes
(American Physical Society, 2000)We predict new forms of carbon consisting of one- and two-dimensional networks of interlinked single-wall carbon nanotubes, some of which are energetically more stable than van der Waals packing of the nanotubes on a ... -
Quantum point contact on graphite surface
(American Physical Society, 1998)The conductance through a quantum point contact created by a sharp and hard metal tip on the graphite surface has features which to our knowledge have not been encountered so far in metal contacts or in nanowires. In this ... -
Vibrations of the cubane molecule: inelastic neutron scattering study and theory
(Elsevier, 1999-08-13)Cubane (C8H8) is an immensely strained molecule whose C-C-C bond angle is 90 degrees rather than 109.5 degrees as expected for sp(3) bonding of carbon. We have measured the intramolecular vibrational spectrum of cubane ...
