  Title The effect of temperature on the structural, electronic and optical properties of sp3-rich amorphous carbon Type A1 Journal article
  Year (down) 2008 Publication Journal of physics : condensed matter Abbreviated Journal J Phys-Condens Mat  
  Volume 20 Issue 3 Pages 035216,1-6  
  Keywords A1 Journal article; Electron microscopy for materials research (EMAT)  
  Abstract The effect of temperature on the structural, electronic and optical properties of dense tetrahedral amorphous carbon made of similar to 80% sp(3)-bonded atoms is investigated using a combination of the classical Monte Carlo technique and density functional theory. A structural transformation accompanied by a slight decrease of the sp(3) fraction is evidenced above a temperature of about 600 degrees C. A structural analysis in combination with energy-loss near-edge structure calculations shows that beyond this temperature, the sp(2)-bonded C sites arrange themselves so as to enhance the conjugation of the p electrons. The Tauc optical band gap deduced from the calculated dielectric function shows major changes beyond this temperature in accordance with experimental results. Energy-loss near-edge structure and band gap calculations additionally reveal a massive destabilization of the of sp(3) bonding phase in favour of sp(2) bonding at a temperature of about 1300 degrees C which agrees very well with the reported value of 1100 degrees C.
