| Description | Model of the DLC band structure that took into account valence to conduction band transitions, pi-to-pi* and sigma-to-sigma*, and valence to extended states transitions sigma-to-xi* was confirmed by using the synchrotron ellipsometry at BESSY II in the range 5–30 eV combined with table-top ellipsometry and spectrophotometry in UV-IR range. The range up to 30 eV covered all the transitions from valence to conduction bands because the maximum energy transition of pi-to-pi* and sigma-to-sigma* were 9.03 and 28.1 eV, respectively. The band gaps of these transitions were 0.75 and 4.74 eV, respectively. |
