Density functional theory based on ab initio method was performed to study the chemisorption behavior of a small fullerene molecule
C28
on the Si(001)-c(2×1) surface.The structural changes of the substrate and fullerene
adsorption energies
charge transfer and electronic density of states were analyzed.The results indicate that the strong interactions take place between C28 and Si(001) surface.The substrate and fullerene molecule undergo the lattice relaxation and structural deformation.The strongest chemisorption occurs at the trench site and the adsorption energy is up to 5.00 eV.The conductivity of Si(001) surface is significantly improved upon C28 adsorption.
