CZTS layers formed under sulfur-limited conditions at above atmospheric pressure
(Elsevier Sci Ltd, 2019)
In this study CZTS thin films were grown by a two-stage process that involved sequential sputter deposition of metallic Cu, Zn, and Sn layers on Mo coated glass substrates followed by RTP annealing in a sulfur atmosphere ...
A research on growth and characterization of CdS:Eu thin films
(Springer Heidelberg, 2019)
Chemical spray pyrolysis-grown CdS thin films including various quantities of Eu atoms (from 0 to 10at.%) were synthesized on glass slides. the detailed physical properties of the produced CdS and CdS:Eu thin films were ...
A detailed research for determination of Bi/Ga partial substitution effect in Bi-2212 superconducting matrix on crucial characteristic features
(Elsevier Science Sa, 2019)
This multidisciplinary study paves way to investigate the crucial of fundamental characteristic properties including the bulk density, electrical, superconducting, flux pinning mechanism, crystal structure quality and ...
Electronic transport and resonant tunneling properties of hyperbolic poschl-teller double-barrier structures
(Taylor & Francis Inc, 2019)
The ballistic electron transport characteristics of hyperbolic Poschl-Teller double-barrier resonant tunneling structures are investigated. the transmission coefficient and the current density-voltage characteristic in ...
Surface modification of CBD-grown CdS thin films for hybrid solar cell applications
(Elsevier Gmbh, 2019)
The influences of interfacial modification by various dyes (Eosin-Y, D205, N719 and N3) on structural, morphological, optical and electrical properties of CdS-based hybrid solar cells are investigated. Structural properties ...
Determination of hypertension disease using chirp z-transform and statistical features of optimal band-pass filtered short-time photoplethysmography signals
(Iop Publishing Ltd, 2020)
Hypertension is the condition where the normal blood pressure is high. This situation is manifested by the high pressure of the blood in the vein towards the vessel wall. Hypertension mostly affects the brain, kidneys, ...
Fabrication and characterization of Au/n-ZnO/p-Si/Al sandwich device with Sol-gel spin coating method
(Springer, 2019)
ZnO thin films with the n-type properties were obtained on the p-Si substrates for multi-layered sandwich device depositing by sol-gel method. Au and Al were conducted on two side of hetero-junction by PVD technique. From ...
Use of the cold substrate method for biomaterials: the dtructural and biological properties of the Ag layers deposited on Ti-6Al-4V
(Springer, 2020)
Silver nanofilms were vacuum-deposited on Ti-6Al-4V substrates at low (< 300 K) temperatures to improve their biocompatibility. After the surface of the Ti-6Al-4V samples was coated with Ag over the temperature range from ...
Determination of optimum Er-doping level to get high transparent and low resistive Cd1-xErxS thin films
(Springer, 2019)
Cd1-xErxS (x=0, 0.02, 0.04, 0.06, 0.08 and 0.10) thin films were produced by a chemical route on glass slides. the structural, morphological, optical and electrical properties of the grown samples were studied to obtain ...
The comparison of levitation and lateral force of bulk and cut-pasted bulk GdBCO samples at different temperatures
(Elsevier Science Sa, 2020)
In this work, in the first time, we have investigated the levitation and lateral force properties of bulk and cut-pasted bulk GdBCO samples at different temperatures and different cooling heights (CH) to determine the ...
