    • Cucurbit [7] uril-threaded fluorene-thiophene-based conjugated polyrotaxanes 

      Idris, M.; Bazzar, M.; Guzelturk, B.; Demir, Hilmi Volkan; Tuncel, D. (Royal Society of Chemistry, 2016)
      Here we investigate the effect of cucurbit[7]uril (CB7) on the thermal and optical properties of fluorene-thiophene based conjugated polyelectrolytes. For this purpose, poly(9,9′-bis(6′′-(N,N,N-trimethylammonium)hexyl)fl ...
    • Investigation of p-type depletion doping for InGaN/GaN-based light-emitting diodes 

      Zhang, Y.; Zhang Z.-H.; Tan S.T.; Hernandez-Martinez, P. L.; Zhu B.; Lu S.; Kang, X. J.; Sun, X. W.; Demir, Hilmi Volkan (American Institute of Physics Inc., 2017)
      Due to the limitation of the hole injection, p-type doping is essential to improve the performance of InGaN/GaN multiple quantum well light-emitting diodes (LEDs). In this work, we propose and show a depletion-region ...
    • Nonradiative recombination-Critical in choosing quantum well number for InGaN/GaN light-emitting diodes 

      Zhang, Y.P.; Zhang, Z.-H.; Liu W.; Tan, S.T.; Ju, Z.G.; Zhang X.L.; Ji, Y.; Wang L.C.; Kyaw, Z.; Hasanov, N.; Zhu, B.B.; Lu, S.P.; Sun X.W.; Demir, Hilmi Volkan (Optical Society of American (OSA), 2015)
      In this work, InGaN/GaN light-emitting diodes (LEDs) possessing varied quantum well (QW) numbers were systematically investigated both numerically and experimentally. The numerical computations show that with the increased ...
