Monolayer diboron dinitride: Direct band-gap semiconductor with high absorption in the visible range
(AMER PHYSICAL SOC, 2020)
We predict a two-dimensional monolayer polymorph of boron nitride in an orthorhombic structure (o-B2N2) using first-principles calculations. Structural optimization, phonon dispersion, and molecular dynamics calculations ...
Calculations of Double Differential Deuteron Emission Cross Sections at 62 MeV Proton Induced Reactions
(Springer, 2013)
In this study, double differential deuteron emission cross sections for Al-27, Fe-54,Fe-56, Au-197, Pb-208 and Bi-209 target nuclei have been calculated by the TALYS code at 62 MeV proton energy. The use of TALYS involved ...
The Structural and Electrical Study of Lu-Doped YBCO System
(Springer, 2013)
We have prepared a series of bulk superconducting samples with the nominal composition of Y1-xLuxBa2 Cu3Oy (where x = 0.0, 0.05, 0.1, 0.2 and 0.3) by the conventional solid-state reaction method. The samples were characterized ...
Calculations of double-differential triton emission cross sections at 62-MeV proton-induced reactions
(Pleiades Publishing Inc, 2014)
Double-differential cross sections (d (2) sigma/d Omega dE >) have been calculated and analyzed for triton production in proton-induced reactions on Al-27, Fe-54,Fe-56, Au-197, and Pb-208 target nuclei at incident energy ...
Improvement of the Nature of Indentation Size Effect of Bi-2212 Superconducting Matrix by Doped Nd Inclusion and Theoretical Modeling of New Matrix
(Springer, 2014)
Neodmium (Nd) inclusions at different stoichiometric ratios (x=0.0, 0.001 %, 0.005 %, 0.01 %, 0.05 %, 0.1 %) are doped in the Bi-2212 superconducting samples and the samples obtained are subjected to the sintering process ...
Comparison of fission barrier and level density models for (alpha,f) reaction of some heavy nuclei
(Pergamon-Elsevier Science Ltd, 2014)
In this work, alpha induced fission reactions for some heavy nuclei (Th-232, U-235, U-238, Np-237 and Pu-238) are calculated based on both fission barrier models and level density models by using the TALYS 1.2 code. The ...
