The effects of substrates with technological interest for solar cell industry are examined on the plasmonic properties of Ag nanoparticles fabricated by dewetting technique. Both surface matching (boundary element) and propagator (finite difference time domain) methods are used in numerical simulations to describe plasmonic properties and to interpret experimental data. The uncertainty on the locations of nanoparticles by the substrate in experiment is explained by the simulations of various Ag nanoparticle configurations. The change in plasmon resonance due to the location of nanoparticles with respect to the substrate, interactions among them, their shapes, and sizes as well as dielectric properties of substrate are discussed theoretically and implications of these for the experiment are deliberated.

Efficient Numerical Algorithm for Cascaded Raman Fiber Lasers Using a Spectral Method
Tarman, Işık Hakan (Institute of Electrical and Electronics Engineers (IEEE), 2009-07-01)
Over recent decades, fiber Raman lasers (FRLs) have received much attention from researchers and have become a challenge for them both numerically and experimentally. The equations governing the FRLs are in the form of a first-order system of nonlinear two-point boundary-value ordinary differential equations. In this paper, an algorithm for solving this system of differential equations using a spectral method, namely Chebyshev pseudospectral method, is presented in detail and then numerical simulations are ...
Molecular-dynamics simulation of the structural stability, energetics, and melting of Cu-n(n=13-135) clusters
Ozdogan, C; Erkoç, Şakir (Springer Science and Business Media LLC, 1997-08-01)
Cluster properties of copper have been investigated using the Molecular-Dynamics MD technique. The structural stability and energetics of spherical Cu, (n = 13 - 135) clusters have been investigated at temperatures T = 1 K and T = 300 K. It has been found that the average interaction energy per atom in the cluster decreases and reaches an asymptotic value as cluster size increases. The melting behaviour of clusters n = 13 and n = 55 have been investigated. It has been found that the melting temperature decr...
A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons
Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01)
The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
Improving the absorption of solar cells using antenna-inspired cavities
Karaosmanoğlu, Barışcan; Tuygar, Emre; Topçuoğlu, Ulaş; Ergül, Özgür Salih (Wiley, 2019-08-01)
We present new types of nanocavities to improve the absorption of solar cells for energy harvesting in wide frequency ranges of the optical spectrum. Using a full‐wave approach, as opposed to the commonly used ray‐based modeling of the light, antenna‐inspired cavities with horn shapes are proposed and introduced. The effectiveness of the designed cavities is demonstrated in comparison to the conventional textures involving inverted pyramids and nanocones. Highly accurate numerical results show that solar‐ce...
Efficient computation of 2D point-spread functions for diffractive lenses
Ayazgok, Suleyman; Öktem, Sevinç Figen (The Optical Society, 2020-01-10)
Diffractive lenses, such as Fresnel zone plates, photon sieves, and their modified versions, have been of significant recent interest in high-resolution imaging applications. As the advent of diffractive lens systems with different configurations expands, the fast and accurate simulation of these systems becomes crucial for both the design and image reconstruction tasks. Here we present a fast and accurate method for computing the 2D point-spread function (PSF) of an arbitrary diffractive lens. The method i...
