    • Binary coded identification of industrial chemical vapors with an optofluidic nose 

      Adamu, A. I.; Ozturk, F. E.; Bayındır, Mehmet (OSA - The Optical Society, 2016)
      An artificial nose system for the recognition and classification of gas-phase analytes and its application in identifying common industrial gases is reported. The sensing mechanism of the device comprises the measurement ...

    • Many-body properties of a disordered charged Bose gas superlattice 

      Tanatar, Bilal; Das, A. K. (Academic Press, 2000)
      We study some many-body properties of a disordered charged Bose gas (CBG) superlattice-an infinite array of CBG layers each of which containing disorder. The latter is assumed to cause collisions with the charged bosons, ...

    • P-doping-free InGaN/GaN light-emitting diode driven by three-dimensional hole gas 

      Zhang, Z.-H.; Tiam Tan, S.; Kyaw, Z.; Liu W.; Ji, Y.; Ju, Z.; Zhang X.; Wei Sun X.; Volkan Demir H. (2013)
      Here, GaN/AlxGa1-xN heterostructures with a graded AlN composition, completely lacking external p-doping, are designed and grown using metal-organic-chemical-vapour deposition (MOCVD) system to realize three-dimensional ...

    • Real-space condensation in a dilute Bose gas at low temperature 

      Kulik, I. O. (Natsional'na Akademiya Nauk Ukrainy, 2001)
      We show with a direct numerical analysis that a dilute Bose gas in an external potential - which is choosen for simplicity as a radial parabolic well - undergoes at certain temperature Tc a phase transition to a state ...

    • Visible photoluminescence from SiOx films grown by low temperature plasma enhanced chemical vapor deposition 

      Timofeev, F. N.; Aydınlı, Atilla; Ellialtioglu, R.; Turkoglu, K.; Gure, M.; Mikhailov, V. N.; Lavrova, O. A. (Pergamon Press, 1995)
      a-SiOx films of varying stoichiometry have been prepared by low temperature plasma enhanced chemical vapor deposition. The majority of films showed photoluminescence (PL) and films prepared in a narrow range of gas flows ...

    • VOC gas leak detection using pyro-electric infrared sensors 

      Erden, Fatih; Soyer, E. B.; Toreyin, B. U.; Çetin, A. Enis (IEEE, 2010)
      In this paper, we propose a novel method for detecting and monitoring Volatile Organic Compounds (VOC) gas leaks by using a Pyro-electric (or Passive) Infrared (PIR) sensor whose spectral range intersects with the absorption ...
