摘要
The ultrafast laser ablation of a carbon target in ambient Ar gas at a pressure of 1-100 Torr resulted in the formation of a low-density (2 - 10) x 10(3) g/cm(3) cluster-assembled carbon nanofoam with a significant fraction of sp(3)-bonding and a resistivity of (1 - 3) x 10(9) Omega cm at room temperature, similar to that of diamond-like carbon film. In this paper we present the structural analysis of the foam based on TEM and SEM images as well as X-ray scattering data and electron energy loss spectra.
