    • Crystallization of Ge in SiO2 matrix by femtosecond laser processing 

      Salihoglu, O.; Kürüm, U.; Yaglioglu, H. G.; Elmali, A.; Aydinli, A. (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 ...
    • Dc-switchable and single-nanocrystal-addressable coherent population transfer 

      Gunceler, D.; Bulutay, C. (2010)
      Achieving coherent population transfer in the solid-state is challenging compared to atomic systems due to closely spaced electronic states and fast decoherence. Here, within an atomistic pseudopotential theory, we offer ...
    • A figure of merit for optimization of nanocrystal flash memory design 

      Dâna, A.; Akca, I.; Aydinli, A.; Turan, R.; Finstad, T. G. (2008)
      Nanocrystals can be used as storage media for carriers in flash memories. The performance of a nanocrystal flash memory depends critically on the choice of nanocrystal size and density as well as on the choice of tunnel ...
    • Ge nanocrystals embedded in ultrathin Si3N4 multilayers with SiO2 barriers 

      Bahariqushchi R.; Gundogdu S.; Aydinli A. (Academic Press, 2017)
      Multilayers of germanium nanocrystals (NCs) embedded in thin films of silicon nitride matrix separated with SiO2 barriers have been fabricated using plasma enhanced chemical vapor deposition (PECVD). SiGeN/SiO2 alternating ...
    • Low dimensional structures for optical and electrical applications 

      Akça, İmran (Bilkent University, 2008)
      Low dimensional structures such as quantum dots have been particularly attractive because of their fundamental physical properties and their potential applications in various devices in integrated optics and microelectronics. ...
    • Matrix density effect on morphology of germanium nanocrystals embedded in silicon dioxide thin films 

      Alagoz, A. S.; Genisel, M. F.; Foss, Steinar; Finstad, T. G.; Turan, R. (Materials Research Society, 2011)
      Flash type electronic memories are the preferred format in code storage at complex programs running on fast processors and larger media files in portable electronics due to fast write/read operations, long rewrite life, ...
    • Nanofibrous nanocomposites via electrospinning 

      Deniz, Ali Ekrem (Bilkent University, 2011)
      In recent years, numerous studies have been reported for fabrication of composite nanofibers from polymeric and inorganic materials by using electrospinning method. In the first part of this study, TiO2 and ZnO ...
    • Photoluminescent electrospun polymeric nanofibers incorporating germanium nanocrystals 

      Ortaç, B.; Kayaci, F.; Vural, H. A.; Deniz, A. E.; Uyar T. (Elsevier, 2013)
      The photoluminescent germanium nanocrystals (Ge-NCs) were successfully incorporated into electrospun polymeric nanofiber matrix in order to develop photoluminescent nanofibrous composite web. In the first step, the synthesis ...
