    • Effects of Alkali Metallization on the Luminescence Degradation of Porous Silicon 

      Özer, Mehmet; Kayahan, Ersin; Oral, Zehra Banu (Polish Acad Sciences Inst Physics, Al Lotnikow 32-46, Pl-02-668 Warsaw, Poland, 2012-01)
      In this study, change in the intensity and stability of photoluminescence obtained by porous silicon were investigated with illumination time and metallization state. The porous silicon samples were metallized by immersing ...
    • Excitation energy-dependent nature of Raman scattering spectrum in GaInNAs/GaAs quantum well structures 

      Erol, Ayşe; Akalın, Elif; Sarcan, Fahrettin; Dönmez, Ömer; Akyüz, Sevim; Arıkan, Mehmet Çetin; Puustinen, Janne; Guina, Mircea (Springer, 233 Spring St, New York, Ny 10013 Usa, 2012-11-28)
      The excitation energy-dependent nature of Raman scattering spectrum, vibration, electronic or both, has been studied using different excitation sources on as-grown and annealed n- and p-type modulation-doped Ga1 -aEuro ...
