    • Laser induced sponge-like Si in Si-rich oxides for photovoltaics 

      Gundogdu, S.; Sungur Ozen, E.; Hübner, R.; Heinig, K.H.; Aydinli, A. (Optical Society of American (OSA), 2013)
      We show that a sponge-like structure of interconnected Si nanowires embedded in a dielectric matrix can be obtained by laser annealing of silicon rich oxides (SRO). Due to quantum confinement, the large bandgap displayed ...
    • Raman studies of doped polycrystalline silicon from laser-annealed, doped a-Si:H 

      Compaan, A.; Savage, M. E.; Aydinli, A.; Azfar, T. (Pergamon Press, 1994)
      We have used Raman scattering to follow the progress of multiple-pulse (sub-melt-threshold) laser annealing in doped hydrogenated amorphous silicon films (a-Si:H) on glass. In phosphorous-doped a-Si:H the Raman signal shows ...
