    • Crystallization of Ge in SiO2 matrix by femtosecond laser processing 

      Salihoglu, O.; Kürüm, U.; Yaglioglu, H. G.; Elmali, A.; Aydınlı, Atilla (American Vacuum Society, 2012-01-19)
      Germanium nanocrystals embedded in a siliconoxide matrix has been fabricated by single femtosecond laser pulse irradiation of germanium doped SiO2 thin films deposited with plasma enhanced chemical vapor deposition. SEM ...

    • Electrochemically tunable ultrafast optical response of graphene oxide 

      Kürüm, U.; Ekiz, O. Ö.; Yaglioglu, H. G.; Elmali, A.; Ürel, M.; Güner, H.; Mızrak, A. K.; Ortaç, B.; Dâna, A. (A I P Publishing LLC, 2011)
      We demonstrate reversible and irreversible changes in the ultrafast optical response of multilayer graphene oxide thin films upon electrical and optical stimulus. The reversible effects are due to electrochemical modification ...

    • Femtosecond laser crystallization of amorphous Ge 

      Salihoglu, O.; Kürüm, U.; Yaglıoglu, G. H.; Elmali, A.; Aydınlı, Atilla (American Institute of Physics, 2011)
      Ultrafast crystallization of amorphous germanium (a-Ge) in ambient has been studied. Plasma enhanced chemical vapor deposition grown a-Ge was irradiated with single femtosecond laser pulses of various durations with a range ...
