Structure and stability of solid C36

Structure and stability of synthesized C36 solid @C. Piskoti, J. Yarger, and A. Zettl, Nature ~London! 393, 771 ~1998!# is investigated using a generalized tight-binding molecular-dynamics method. Out of the many solid forms considered, the most stable structure consists of a polymeric phase of C36 with mixed sp 2 and sp bonding for the atoms. The cross-linking is found to be across the hexagon...

Scanning Tunneling Spectroscopy of C36

The local density of electronic states NsEd has been measured on C36 thin films using scanning tunneling spectroscopy (STS). A 0.8 eV energy gap and sharp features in NsEd with widths as small as 0.2 eV can be ascribed to the discrete molecular energy levels predicted for the C36 molecule, broadened by intermolecular interactions. However, a more complete agreement between the experimental resu...

Solid C36 as hexaclathrate form of carbon

The structure and stability of the newly synthesized C36 solid is investigated using a generalized tightbinding molecular-dynamics method. Symmetry and electronic structure analysis point to a new form of carbon clathrate containing C36 fullerenes as building blocks. All of its atoms have sp 3 bonding and the structure has exact D6h symmetry. This is consistent with the electron-diffraction pat...

Solid C36 : Crystal structures, formation, and effects of doping

We employ plane-wave pseudopotential density functional calculations to show that the lowest energy D6h C36 crystal is a highly bonded network of hexagonal planes of C36 units with AB stacking. This crystal is significantly more dense and lower in energy than previously proposed structures. We demonstrate that Na is the largest alkali atom that can be intercalated into the crystal structure wit...
