    • An efficient non-Lambertian organic light-emitting diode using imprinted submicron-size zinc oxide pillar arrays 

      Liu, S. W.; Wang, J. X.; Divayana, Y.; Dev, K.; Tan S.T.; Demir, Hilmi Volkan; Sun, X. W. (AIP, 2013)
      We report phosphorescent organic light-emitting diodes with a substantially improved light outcoupling efficiency and a wider angular distribution through applying a layer of zinc oxide periodic nanopillar arrays by pattern ...
    • Graded-host phosphorescent light-emitting diodes with high efficiency and reduced roll-off 

      Liu, S. W.; Sun, X. W.; Demir, Hilmi Volkan (A I P Publishing LLC, 2012)
      We demonstrated graded-host phosphorescent organic light-emitting diodes with high efficiency and reduced efficiency roll-off. The emissive layer of the graded host device consists of both electron and hole transport type ...
    • Graph analytics accelerators for cognitive systems 

      Ozdal, M. M.; Yesil, S.; Kim, T.; Ayupov, A.; Greth, J.; Burns, S.; Ozturk, O. (Institute of Electrical and Electronics Engineers, 2017)
      Hardware accelerators are known to be performance and power efficient. This article focuses on accelerator design for graph analytics applications, which are commonly used kernels for cognitive systems. The authors propose ...
