The effects of gold (Au) nanoparticles (NPs) with different morphologies (star, rod, sphere) incorporated into buffer layer, poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS), of polymer-based organic solar cells (OSCs) were investigated. Solar cells having gold nanoparticles exhibited significant improvement in device efficiency relative to the reference device. The observed improvement is most likely due to the surface plasmon and enhanced light reflection and scattering properties of the Au NPs. The power conversion efficiency (PCE) is increased ca. 29% with Au nanostars, ca. 14% with Au nanorods and 11% with Au nanospheres compared to the device with no Au NP (reference device). Au nanostars provide the strongest contribution to the efficiency among all NP morphologies studied as they have large size, sharp features, and strongest localized surface plasmon resonance effect associate with their morphology.

RAMAN-SPECTROSCOPY OF SOFT AND RIGID MODES IN FERROELECTRIC TLINS2 BURLAKOV, VM; RYABOV, AP; YAKHEEV, MP; VINOGRADOV, EA; MELNIK, NN; Hasanlı, Nızamı (Wiley, 1989-06-01) Low‐frequency Raman spectra of a TlInS2 single crystal in the vicinity of a ferroelectric phase transition are reported. In the ferroelectric phase a soft mode interacting with some rigid modes is observed. The temperature dependence of the soft mode frequency is found to be proportional to (Tc – T)1/2. An unusual behaviour of the rigid mode (ω = 20 cm−1) is observed. This fact is interpreted in terms of inherent lattice defects which cause nonhomogeneous broadening.
Refractive index, static dielectric constant, energy band gap and oscillator parameters of Ga2SeS single crystals Qasrawi, A. F.; Hasanlı, Nızamı (Wiley, 2007-09-01) The optical properties of Bridgman method grown Ga2SeS crystals have been investigated by means of room-temperature transmittance and reflectance spectral analysis. The optical data have revealed direct and indirect allowed transition band gaps of 2.49 and 2.10 eV, respectively. The room-temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as...
Fabrication of SiO2-stacked diamond membranes and their characteristics for microelectromechanical applications Bayram, Barış (Elsevier BV, 2011-04-01) Diamond is a promising microelectromechanical systems (MEMS) material due to its high Young's Modulus and very large thermal conductivity. In this work, ultrananocrystalline diamond was stacked between silicon dioxide to form thermally-stable and robust membranes. These SiO2-stacked diamond layers were processed into MEMS-compatible membranes. For comparison, membranes composed of only SiO2 were fabricated as well. The structural characteristics of these membranes are compared and analyzed for membranes of ...
Indium rich InGaN solar cells grown by MOCVD Cakmak, H.; Arslan, Engin; Rudzinski, M.; Demirel, P.; Ünalan, Hüsnü Emrah; Strupinski, W.; Turan, Raşit; ÖZTÜRK, MEHMET AKİF; ÖZBAY, Ekmel (Springer Science and Business Media LLC, 2014-08-01) This study focuses on both epitaxial growths of InxGa1-xN epilayers with graded In content, and the performance of solar cells structures grown on sapphire substrate by using metal organic chemical vapor deposition. The high resolution X-ray and Hall Effect characterization were carried out after epitaxial InGaN solar cell structures growth. The In content of the graded InGaN layer was calculated from the X-ray reciprocal space mapping measurements. Indium contents of the graded InGaN epilayers change from ...
Phonon dispersions and elastic constants of disordered Pd-Ni alloys Kart, SO; Tomak, Mehmet; Cagin, T (Elsevier BV, 2005-01-31) Phonon frequencies of Pd-Ni alloys are calculated by molecular dynamics (MD) simulation. Lattice dynamical properties computed from Sutton-Chen (SC) and quantum Sutton-Chen (Q-SC) potentials as a function of temperature are compared with each other. We present all interatomic force constants up to the 8th nearest-neighbor shell obtained by using the calculated potential. Elastic constants evaluated by two methods are consistent with each other. The transferability of the potential is also tested. The result...
