    • Atomic layer deposited Al 2O 3 passivation of type II InAs/GaSb superlattice photodetectors 

      Salihoğlu, Ömer; Muti, Abdullah; Kutluer, Kutlu; Tansel, T.; Turan, R.; Kocabaş, Coşkun; Aydınlı, Atilla (AIP, 2012)
      Taking advantage of the favorable Gibbs free energies, atomic layer deposited (ALD) aluminum oxide (Al 2O 3) was used as a novel approach for passivation of type II InAs/GaSb superlattice (SL) midwave infrared (MWIR) single ...
    • Electrical performance of InAs/AlSb/GaSb superlattice photodetectors 

      Tansel, T.; Hostut M.; Elagoz, S.; Kilic A.; Ergun, Y.; Aydinli, A. (Academic Press, 2016)
      Temperature dependence of dark current measurements is an efficient way to verify the quality of an infrared detector. Low dark current density values are needed for high performance detector applications. Identification ...
    • Electronic and optical properties of 4.2 μm"N" structured superlattice MWIR photodetectors 

      Salihoglu, O.; Hostut M.; Tansel, T.; Kutluer, K.; Kilic A.; Alyoruk, M.; Sevik, C.; Turan, R.; Ergun, Y.; Aydinli, A. (Elsevier, 2013)
      We report on the development of a new structure for type II superlattice photodiodes that we call the "N" design. In this new design, we insert an electron barrier between InAs and GaSb in the growth direction. The barrier ...
    • A hole modulator for InGaN/GaN light-emitting diodes 

      Zhang, Z-H.; Kyaw, Z.; Liu W.; Ji Y.; Wang, L.; Tan S.T.; Sun, X. W.; Demir, H. V. (American Institute of Physics, 2015)
      The low p-type doping efficiency of the p-GaN layer has severely limited the performance of InGaN/GaN light-emitting diodes (LEDs) due to the ineffective hole injection into the InGaN/GaN multiple quantum well (MQW) active ...
    • Skin-like self-assembled monolayers on InAs / GaSb superlattice photodetectors 

      Salihoglu, O.; Muti, A.; Kutluer, K.; Tansel, T.; Turan, R.; Aydinli, A. (IOP Institute of Physics Publishing, 2012)
      We report on the effects of monolayer (ML) thick skin-like octadecanethiol (ODT, CH 3[CH 2] 17SH) on type-II InAs/GaSb MWIR photodetectors. Circumventing the ageing effects of conventional sulfur compounds, we use ODT, a ...
