The influence of Er3+ doping on the structural and optical properties of CeO2 thin films grown by PED
(Elsevier Science Bv, 2013)
Erbium doped CeO2 thin films were deposited on both Corning glass substrates and indium doped tin oxide (ITO) coated glass substrates by pulsed e-beam deposition (PED) method at room temperature. Structural features of Er ...
Higher dimensional cylindrical or Kasner type electrovacuum solutions
(Springer/Plenum Publishers, 2013)
We consider a dimensional Kasner type diagonal spacetime where metric functions depend only on a single coordinate and electromagnetic field shares the symmetries of spacetime. These solutions can describe static cylindrical ...
Ab initio study on the rare-earth iron-pnictides RFeAsO (R = Pr, Nd, Sm, Gd) in the low-temperature Cmma phase
(Iop Publishing Ltd, 2014)
We present density functional theory calculations on the iron-based pnictides RFeAsO (R = Pr, Nd, Sm, Gd). The calculations have been carried out using plane waves and the projector augmented wave (PAW) pseudopotential ...
Structure and photovoltaic properties of Ag/p-CuPc/a-Si/c-Si/Ag organic-inorganic hybrid heterojunction fabricated by chemical spray pyrolysis technique
(Elsevier Science Bv, 2013)
This investigation refers to the fabrication of an organic-inorganic hybrid heterojunction photovoltaic device. Heterojunctions PV devices were fabricated by growing p-type organic CuPc films onto inorganic amorphous silicon ...
Binding energy of 2p-bound state of a hydrogenic donor impurity in a GaAs/Ga1-xAlxAs spherical quantum dot under hydrostatic pressure
(Elsevier, 2014)
By using a variational procedure within the effective mass approximation, we calculated the 2p state binding energy, E-2pha(x,P), and the binding energy turning point, R-2pEbT (X, P) of a hydrogenic donor impurity located ...
The diamagnetic susceptibility of hydrogenic donor in two-dimensional semiconductors with anisotropic effective mass of carriers
(Academic Press Ltd- Elsevier Science Ltd, 2012)
In this study, the effects of quantum confinement and effective mass anisotropy parameter on the diamagnetic susceptibility of a hydrogenic donor placed in GaAs. Si, and Ge quantum wells with infinite confinement potential ...
Low temperature crystallization of amorphous silicon by gold nanoparticle
(Elsevier, 2013)
Single crystalline Si thin film fabricated on glass substrate by a process called Solid Phase Crystallization (SPC) is highly desirable for the development of high efficiency and low cost thin film solar cells. However, ...
The Saricicek howardite fall in Turkey: Source crater of HED meteorites on Vesta and impact risk of Vestoids
(Wiley, 2019)
The Saricicek howardite meteorite shower consisting of 343 documented stones occurred on September 2, 2015 in Turkey and is the first documented howardite fall. Cosmogenic isotopes show that Saricicek experienced a complex ...
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, ...
