We present full-wave electromagnetic optimization of corrugated metallic sheets to achieve maximum power focusing at desired locations when illuminated by plane waves. The corrugations are freely applied by moving the discretization nodes, leading to huge optimization spaces that are scanned by employing genetic algorithms. The required simulations are performed accurately and efficiently via the method of moments or the multilevel fast multipole algorithm. Hundreds of thousands of simulations are performed to demonstrate the feasibility of strong optical focusing, even with relatively small sheets in terms of wavelength. The corrugated sheets can be useful in various applications, such as energy harvesting, solar cells, imaging, and optical sensing.

Temperature effect on dark electrical conductivity, Hall coefficient, space charge limited current and photoconductivity of TlGaS2 single crystals Qasrawi, AF; Hasanlı, Nızamı (IOP Publishing, 2005-05-01) The dark electrical conductivity, Hall coefficient, space charge limited current, and illumination and temperature dependences of the photocurrent of TIGaS2 single crystals in the temperature regions of 100-350, 200-350, 200-290 and 100-350 K, respectively, have been measured and analysed. The Hall coefficient measurements revealed the extrinsic type of conduction with conductivity-type conversion from p- to n-type at a critical temperature of 315 K. The temperature dependence of the dark electrical conduct...
Optical constants of Tl4Ga3InSe8 layered single crystals Goksen, K.; Hasanlı, Nızamı (Elsevier BV, 2007-11-15) The optical properties of Tl(4)Ga(3)lnSe(8) layered single crystals have been studied by means of transmission and reflection measurements in the wavelength range of 500-1100 run. The analysis of the room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 1.94 and 2.20 eV, respectively. Transmission measurements carried out in the temperature range of 10-300 K revealed that the rate of change of the indirect band gap with temperature i...
Optoelectronic and electrical properties of TlGaS2 single crystal Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2005-10-01) The optoelectronic and electrical properties of TIGaS2 single crystals have been investigated by means of room temperature transmittance and reflectance spectral analysis, Hall coefficient, dark electrical resistivity and photocurrent measurements in the temperature range of 200-350 K. The optical data have revealed an indirect and direct allowed transition band gaps of 2.45 and 2.51 eV, an oscillator and dispersion energy of 5.04 and 26.45 eV, respectively, a static dielectric constant of 6.25 and static r...
Lattice-matched AlInAs-InGaAs mid-wavelength infrared QWIPs: characteristics and focal plane array performance Kaldirim, M.; Arslan, Y.; Eker, S. U.; Beşikci, Cengiz (IOP Publishing, 2008-08-01) The AlInAs/InGaAs material system is promising for mid-wavelength infrared (MWIR) and multi-band quantum well infrared photodetectors (QWIPs) as a lattice-matched alternative to the strained AlGaAs/InGaAs system. In this paper, we report a large format (640 x 512) AlInAs/InGaAs QWIP focal plane array (FPA) with 4.9 mu m cut-off wavelength and assess the performance of this material system for MWIR QWIP applications at both pixel and large format FPA level. We also experimentally demonstrate that the cut-off...
Electrical response of electron selective atomic layer deposited TiO2-x heterocontacts on crystalline silicon substrates Ahiboz, Doguscan; Nasser, Hisham; Aygun, Ezgi; Bek, Alpan; Turan, Raşit (IOP Publishing, 2018-04-01) Integration of oxygen deficient sub-stoichiometric titanium dioxide (TiO2-x) thin films as the electron transporting-hole blocking layer in solar cell designs are expected to reduce fabrication costs by eliminating high temperature processes while maintaining high conversion efficiencies. In this paper, we conducted a study to reveal the electrical properties of TiO2-x thin films grown on crystalline silicon (c-Si) substrates by atomic layer deposition (ALD) technique. Effect of ALD substrate temperature, p...
