(Elsevier B.V., 2012-09)
An ab initio investigation of the optical constants of 9-Methyl-3-Thiophen- 2-YI-Thieno [3,2e] [1,2,4] Thriazolo [4,3c] Pyrimidine-8-Carboxylic Acid Ethyl Ester crystal is performed within a framework of local density ...
Characterisation, analysis and optical properties of nanostructure ZnO using the sol-gel method
(Institution of Engineering and Technology (IET), 2012-02)
Nanostructure ZnO was grown on thin aluminium layer, deposited on silicon substrate using the sol-gel method. The surface morphologies of nanostructure ZnO at different precursor concentrations were studied using scanning ...
Modeling of structural properties of hexagonal semiconductors
(Elsevier B.V., 2013)
Bulk modulus of hexagonal structure semiconductors are calculated by using density functional theory (DFT) of full-potential linear augmented plane wave (FP-LAPW) within general gradient approximation (GGA). In this work, ...
Characteristics of nanostructure silicon photodiode using laser assisted etching
(Elsevier B.V., 2013)
We prepared nanostructures silicon photodiode (nPSi) by using laser assisted etching at fixed current density (30 mA/cm2) with different etching wavelengths of laser diode (532, 650 and 810 nm), a (metal/nanostructure ...
Influence of current density on porous silicon characteristics
(Trans Tech Publications, 2013)
Porous silicon structures have been fabricated by electrochemical etching using different current density. From field emission scanning electron microscope images (FE-SEM) it was observed that more uniform distribution of ...
External temperature and pressure effects on thermodynamic properties and mechanical stability of yttrium chalcogenides YX(X=S, Se and Te)
(Elsevier B.V., 2013)
The full potential linearized augmented plane wave method within the framework of density functional theory is employed to investigate the structural, thermodynamic and elastic properties of the yttrium chalcogenides (YX: ...
Structural, elastic, electronic and optical properties of the newly synthesized monoclinic Zintl phase BaIn₂P₂
(Elsevier, 2014-03)
The present study explores the structural, elastic, electronic and optical properties of the newly synthesized monoclinic Zintl phase BaIn₂P₂ using a pseudopotential plane-wave method in the framework of density functional ...
Evaluate the effects of various surface roughness on the tribological characteristics under dry and lubricated conditions for Al-Si alloy
(Scientific Research Publishing Inc. All rights reserved., 2012-07)
The effect of surface roughness average of hypereutectic aluminum silicon alloys (with 16 wt% Si) on the friction and wear was investigated. Various surface roughness average (Ra) of different degrees was verified as well ...
Alternative-current electrochemical etching of uniform porous silicon for photodetector applications
(Electrochemical Science Group, 2013)
The twining of alternative-current (AC) with electrochemical etching (ECE) to fabricate porous silicon (PS) is studied. The porosity percentage is obtained by gravimetric analysis. The effect of different current densities; ...
Structural and morphological studies of cadmium sulfide nanostructures
(Trans Tech Publications, 2013)
Cadmium sulfide (CdS) nanostructures were prepared with different spin coating speed 1000 and 3000 rpm and molarities of Cd:S to be 1.2 to 0.01 mol/L using sol-gel spin coating technique. It is found that the average grain ...
