    • Effect of the passivation layer on the noise characteristics of mid-wave-infrared InAs / GaSb superlattice photodiodes 

      Tansel, T.; Kutluer, K.; Salihoglu, Ö.; Aydinli, A.; Aslan, B.; Arikan, B.; Kilinc, M. C.; Ergun, Y.; Serincan, U.; Turan, R. (IEEE, 2012)
      The authors describe the noise characterization of a mid-wavelength- infrared (MWIR) photodiode based on indium arsenide and gallium antimonide (InAs/GaSb) superlattice (SL), addressing the influence of different passivation ...
    • High quality single-crystal germanium-on-insulator on bulk Si substrates based on multistep lateral over-growth with hydrogen annealing 

      Yu, H. Y.; Cheng, S. L.; Park, J. H.; Okyay, A., K.; Onbal, M. C.; Ercan, B.; Nishi, Y.; Saraswat, K. C. (American Institute of Physics, 2010-08-09)
      Germanium-on-insulator (GOI) is desired for high performance metal-oxide-semiconductor transistors and monolithically integrated optoelectronics. We demonstrate a promising approach to achieve single-crystal defect-free ...
    • High-quality InP/ZnS nanocrystals with high photometric performance and their application to white quantum dot light-emitting diodes 

      Yang, X.; Tan, S. T.; Demir, Hilmi Volkan; Sun, X. W. (IEEE, 2012)
      Full visible range covering InP/ZnS core-shell nanocrystals with high photometric performance have been prepared. Making use of these nanocrystals, we demonstrate a white quantum dot LED with a high color rendering index ...
    • Quantum dot integrated LEDs using photonic and excitonic color conversion 

      Demir, Hilmi Volkan; Nizamoglu, S.; Erdem, T.; Mutlugun, E.; Gaponik N.; Eychmüller A. (Elsevier, 2011-11-23)
      This review summarizes advantages, recent progress and challenges related to the quickly evolving research field of colloidal quantum dot integrated LEDs based on color conversion. We start with presenting a short general ...
    • Real-time fringe pattern generation with high quality 

      Kang, H.; Yaraş, F.; Onural, L.; Yoshikawa, H. (Optical Society of America, 2009)
      A hologram computation procedure and its GPU implementation are presented. The procedure is based on partitioning. Each segment has an approximate but simpler frequency domain representation. Quality of the results is ...
    • Rethinking social inclusivity: Design strategies for cities 

      Afacan, Yasemin; Afacan, S. O. (ICE Publishing, 2011)
      Cities have become more fragmented due to the increasing urbanisation of many parts of the world. There is more inequality and a growing complexity of social life in cities that leads to social exclusion and increasing ...
    • SAR image reconstruction by EMMP algorithm 

      Uǧur, Salih; Arıkan, Orhan; Gürbüz, A. C. (IEEE, 2012-04)
      In this work, EMMP algorithm is used to solve the SAR image reconstruction problem which is modelled in the compressed sensing context. It is found that the sparsity parameter of the target region is an important parameter ...
    • Selective-area high-quality germanium growth for monolithic integrated optoelectronics 

      Yu, H. Y.; Park, J. H.; Okyay, A., K.; Saraswat, K. C. (Institute of Electrical and Electronics Engineers, 2012-03-02)
      Selective-area germanium (Ge) layer on silicon (Si) is desired to realize the advanced Ge devices integrated with Si very-large-scale-integration (VLSI) components. We demonstrate the area-dependent high-quality Ge growth ...
    • SONIC: streaming overlapping community detection 

      Sarıyüce, A. E.; Gedik, B.; Jacques-Silva, G.; Wu, Kun-Lung; Catalyurek, U.V. (Springer, 2016)
      A community within a graph can be broadly defined as a set of vertices that exhibit high cohesiveness (relatively high number of edges within the set) and low conductance (relatively low number of edges leaving the set). ...
    • Towards a quality service layer for Web 2.0 

      Schaal, M.; Davenport, David; Çevik, Ali Hamdi (Springer, 2011-12)
      Despite the help of search engines and Web directories, identifying high quality content becomes increasingly difficult as the Internet gets ever more crowded with information. Prior approaches for filtering and searching ...
