Conformal cosmological black holes: Towards restoring determinism to Einstein theory
(Springer Heidelberg, 2019)
A widespread solution-generating technique of general relativity consists of conformally transforming known seed solutions. It is shown that these new solutions always solve the field equations of a pathological Brans-Dicke ...
Characterization of one-step deposited Cu2ZnSnS4 thin films derived from a single crystalline powder
(Pergamon-Elsevier Science Ltd, 2019)
In this paper, Cu-deficient and Zn-rich Cu2ZnSnS4 (CZTS) single crystals were successfully grown by Bridgman technique. Following the investigation of structural and photo-electrical properties of the grown CZTS crystal, ...
Symmetry of Brans-Dicke gravity as a novel solution-generating technique
(Amer Physical Soc, 2018)
A symmetry of Brans-Dicke gravity in (electro) vacuo or in the presence of conformally invariant matter is presented and used as a solution-generating technique starting from a known solution as a seed. This novel technique ...
Perfect fluid solutions of Brans-Dicke and f (R) cosmology
(Academic Press Inc Elsevier Science, 2018)
Brans-Dicke cosmology with an (inverse) power-law potential is revisited in the light of modern quintessence and inflation models. A simple ansatz relating scale factor and scalar field recovers most of the known solutions ...
Fabrication of CdSeXTe1-x thin films by sequential growth using double sources
(Elsevier, 2021)
CdSexTe(1-x) (CST) ternary thin films were fabricated by stacking thermally evaporated CdSe and electron beam evaporated CdTe layers. The final structure was achieved in a stoichiometric form of approximately Cd:Se:Te = ...
Investigation of carrier transport mechanisms in the Cu-Zn-Se based hetero-structure grown by sputtering technique
(Canadian Science Publishing, Nrc Research Press, 2018)
In this paper, we present results of the electrical characterization of n-Si/p-Cu-Zn-Se hetero-structure. Sputtered film was found in Se-rich behavior with tetragonal polycrystalline nature along with (112) preferred ...
Structural, spectral and optical properties of rocksalt Al,Mn-doped CdO: experimental and DFT studies
(Springer, 2019)
Nano-crystalline Cd0.95-xMn0.05AlxO (x = 0, 0.02, 0.04, 0.06, 0.08, 0.10) semiconductors were synthesized by sol-gel technique. These samples are characterized via X-ray diffraction (XRD), scanning electron microscope (SEM) ...
An Improved Method for Determination of Refractive Index of Dielectric Films from Reflectance Spectrum by Using the Generalized Morse Wavelet
(Sciendo, 2021)
The Generalized Morse Wavelet (GMW) algorithm was adapted to determine the refractive index of dielectric film from the reflectance spectrum. A theoretically generated reflectance spectrum in the range of 300-1200 nm ...
Hatay İlinde Macera Turizmi Potansiyelinin Coğrafi Yaklaşımla İncelenmesi
(2015)
Karmaşık ve anlaşılması güç güncel bir konu olan macera turizmine ilgi hem Dünya'da, hem de Türkiye'de gün geçtikçe artmaktadır. Yeni turizm nişlerinden biri olarak değerlendirilen macera turizmi, mevcut doğal ve kültürel ...
Ab initio lattice dynamics and thermodynamics of rare-earth hexaborides LaB6 and CeB6
(Amer Physical Soc, 2010)
We have performed an ab initio study of structural, elastic, lattice-dynamical, and thermodynamical properties of rare-earth hexaborides LaB6 and CeB6. The calculations have been carried out within the density-functional ...
