Structural analysis of a carbon foam formed by high pulse-rate laser ablation
Abstract
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)×103 g/cm3 cluster-assembled carbon nanofoam with a significant fraction of sp3-bonding and a resistivity of (1-3)×109 Ωcm 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.
