  • Bor bileşiklerinin yapısal, elektronik ve optiksel özelliklerinin teorik olarak incelenmesi 
    Üstündağ, Mehmet (Sakarya Üniversitesi, 2013)
    Bu tez Bor-V grubu yarı iletken bileşiklerin (BN, BP, BAs, BSb, BBi) yapısal, elektronik ve optiksel özelliklerini bir arada inceleyen ilk çalışmadır. Ayrıca Bor-V grubu bileşiklerin bazı yapısal ve optiksel parametreleri ...
  • Electronic and Magnetic Properties of Ca-Doped Mn-Ferrite 
    Üstündağ, Mehmet (POLISH ACAD SCIENCES INST PHYSICS, 2016)
    Spinel ferrite structures have vast applications, from microwave to radio frequencies. In order to acquire new electronic and optical behavior, divalent cations can be added to normal spinel ferrite structure. This way it ...
  • Electronic and optical properties of BBi and AlBi: Hybrid (YS-PBE0) function 
    Yalçın, Battal Gazi; Bağcı, Sadık; Üstündağ, Mehmet; Aslan, Metin (ELSEVIER SCIENCE BV, 2015)
    III-Bi compounds have been extensively studied in recent years because of their wide applications in optoelectronic devices. Despite the wealth of theoretical works, optical properties of first two members of this family, ...
  • Optical Properties of BN and BBi Compounds 
    Yalçın, Battal Gazi; Üstündağ, Mehmet; Aslan, Metin (POLISH ACAD SCIENCES INST PHYSICS, 2014)
    We have investigated optical properties which are very important for optoelectronic devices, such as laser modulators, photo detectors, optical amplifier and high efficient solar cells of BN and BBi using the density ...
  • Structural and electronic properties of Ga1-xInxAs1-yNy quaternary semiconductor alloy on GaAs substrate 
    Aslan, Metin; Üstündağ, Mehmet; Yalçın, Battal Gazi (ELSEVIER SCIENCE SA, 2012)
    We have presented structural and electronic properties of binary (GaAs, GaN and InAs), ternary (Ga1-xInxAs and GaAs1-yNy) and quaternary (Ga1-xInxAs1-yNy) semiconductor alloys by using a first-principles pseudopotential ...
  • Structural and electronic properties of InNxP1-x alloy in full range (0 <= x <= 1) 
    Metin Aslan; A. H. Reshak; Yalçın, Battal Gazi; Bağcı, Sadık; Üstündağ, Mehmet (TAYLOR & FRANCIS LTD, 2016)
    We have performed first-principles method to investigate structural and electronic properties of InNxP1-x ternary semiconductor alloy in full range (0 <= x <= 1) using density functional theory. We have used modified ...
  • The first-principles study on physical properties and phase stability of Boron-V (BN, BP, BAs, BSb and BBi) compounds 
    Üstündağ, Mehmet; Yalçın, Battal Gazi (ELSEVIER, 2014)
    The physical properties of Boron - group V compounds have been investigated systematically by using density functional theory, based on the full-potential linearized augmented plane-wave method. Generalized gradient ...
  • The Optoelectronic Properties of Sb Doped BBi Compounds 
    Üstündağ, Mehmet; Yalçın, Battal Gazi; Aslan, Metin; Bağcı, Sadık (POLISH ACAD SCIENCES INST PHYSICS, 2016)
    We have determined structural, electronic and optical properties of BBi1-xSbx alloy by using density functional theory based on the full potential linearized augmented plane wave method. For the exchange correlation ...
