      We study the band-gap renormalization m a model semiconductor quantum wire due to the exchange-correlation effects among the charge carriers. We construct a two-subband model for the quantum wire, and employ the GW-approximation ...
    • Band-gap renormalization in quantum wires 

      Güven, Kaan; Bennett, C.R.; Tanatar, Bilal (TÜBİTAK, 1999)
      Improved techniques in semiconductor fabrication increased the interest in quantum wire structures, because of their opto-electronic device application possibilities. Many-body interactions among the electrons and holes ...
    • Band-gap renormalization in quasi-one-dimensional electron-hole systems 

      Tanatar, Bilal (Institute of Physics Publishing Ltd, 1996)
      We study the band-gap renormalization (BGR) in semiconductor quantum wires. Assuming an electron-hole system in quasi-equilibrium, we employ the random-phase approximation (RPA) and beyond (e.g., local-field corrections) ...
    • Band-gap renormalization in quasi-one-dimensional systems 

      Tanatar, Bilal (Kluwer Academic Publishers, 1997)
    • Bandwidth improvement in a cMUT array with mixed sized elements 

      Bayram, Can; Olcum, Selim; Şenlik, Muhammed N.; Atalar, Abdullah (IEEE, 2005-09)
      A capacitive micromachined ultrasonic transducer (cMUT) is typically fabricated by concatenation of several cMUT cells with identical physical dimensions. If the membrane thickness is kept fixed, the radius of the cMUT ...
    • Bandwidth selection for kernel density estimation using fourier domain constraints 

      Suhre, A.; Arıkan, Orhan; Çetin, A. Enis (Institution of Engineering and Technology, 2016)
      Kernel density estimation (KDE) is widely-used for non-parametric estimation of an underlying density from data. The performance of KDE is mainly dependent on the bandwidth parameter of the kernel. This study presents an ...
    • Bandwidth, power and noise considerations in airborne cMUTs 

      Şenlik, Muhammed N.; Olcum, Selim; Köymen, Hayrettin; Atalar, Abdullah (IEEE, 2009-09)
      Capacitive micromachined ultrasonic transducers (cMUTs) offer wider bandwidth in air due to their low mechanical impedances. The impedance mismatch between the air and transducer decreases with the smaller device dimensions ...
    • Bandwidth-aware and energy-efficient stream multicasting protocols for wireless multimedia sensor networks 

      Yargıçoğlu, Burcu (Bilkent University, 2010)
      In recent years, the interest in wireless sensor networks has grown and resulted in the integration of low-power wireless technologies with cameras and microphones enabling video and audio transport through a sensor ...
    • Bank lending channel in Turkey 

      Aktaş, Cihan (Bilkent University, 2006)
