Sub-picosecond electron dynamics in polycrystalline diamond films
Original language description
Polycrystalline diamond, as a composite material, primarily consists of sp3 and sp2 hybridized carbon phases in different ratio. The amount of grain boundaries, sp2 non-diamond carbon phase and other defects and impurities play a crucial role in relaxation and recombination of photo-excited charge carriers in diamond films. The transient transmission measurements are performed using non-degenerate pump and probe technique using few cycle laser pulses with temporal resolution of ~15 fs. We show that the initial processes occurring after interaction of light with diamond membranes are sensitive to the sp3/sp2 ratio phases. We propose a simple microscopic model of electron relaxation via sub-gap energy levels caused by surface states, sp2 carbon phase and defects of the crystal lattice of diamond grains.
