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

      Gundogdu, S.; Sungur Ozen, E.; Hübner, R.; Heinig, K.H.; Aydınlı, Atilla (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 ...
