A dual band metamaterial absorber is designed for photovoltaic applications. The novelty of the design provides the absorption of the energy in an ultrathin semiconductor layer. Additionally, dependence of the absorption on the geometric dimensions, polarization, and temperature are also discussed. The results for the thermal characterization of the aforementioned design showed that this absorber operates almost independently from the environmental temperature conditions and the polarization of the light. According to the obtained results, the proposed metamaterial absorber can be a good candidate for the photovoltaic energy generation.

SINGLE-, DUAL-, AND TRIPLE-BAND METAMATERIAL-INSPIRED ELECTRICALLY SMALL PLANAR MAGNETIC DIPOLE ANTENNAS
Turkmen, Oznur; Sayan, Gönül; Ziolkowski, Richard W. (Wiley, 2014-01-01)
The design and performance characteristics of metamaterial-inspired electrically small, single, dual and triple band antennas at the GSM (1.93-1.99 GHz), ISM (2.43-2.4835 GHz), and WiMAX (3.3-3.6 GHz) frequencies are reported. These antennas are based on a coaxially fed printed dipole integrated in a planar configuration with capacitively loaded loops (CLLs) as its near-field resonant parasitic radiators. In the proposed topology, the number of operating frequencies is determined by the number of CLLs. Thes...
QWIP focal plane arrays on InP substrates for single and dual band thermal imagers
Eker, S. U.; Arslan, Y.; Kaldirim, M.; Beşikci, Cengiz (Elsevier BV, 2009-11-01)
Alternative material systems on InP substrate provide certain advantages for mid-wavelength infrared (MWIR), long-wavelength infrared (LWIR) and dual band MWIR/LWIR quantum well infrared photodetector (QWIP) focal plane arrays (FPAs). While InP/InGaAs and InP/InGaAsP LWIR QWIPs provide much higher responsivity, when compared to the AlGaAs/CaAs QWIPs, AllnAs/InGaAs system facilitates completely lattice matched single band MWIR and dual band MWIR/LWIR FPAs.
Stability analysis of graphene nanoribbons by molecular dynamics simulations
Dugan, N.; Erkoç, Şakir (Wiley, 2008-04-01)
In this work, stability of graphene nanoribbons are investigated using molecular dynamics. Simulations include heating armchair and zigzag-edged nanoribbons of widths varying between one and nine hexagonal rings until the bonds between carbon atoms start to break. Breaking temperatures and binding energies per atom for different widths are presented for both armchair and zigzag-edged cases. A nontrivial relation between stability and width is observed and discussed.
Thermally stimulated currents in layered Ga4SeS3 semiconductor
Aytekin, S; Yuksek, NS; Goktepe, M; Hasanlı, Nızamı; Aydinli, A (Wiley, 2004-10-01)
Thermally stimulated current (TSC) measurements are carried out on nominally undoped Ga4SeS3 layered semiconductor samples with the cur-rent flowing along the c-axis in the temperature range of 10 to 150 K. The results are analyzed according to various methods, such as curve fitting, initial rise and Chen's methods, which seem to be in good agreement with each other. Experimental evidence is found for the presence of three trapping centers in Ga4SeS3 with activation energies of 70, 210 and 357 meV. The calc...
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...
