This paper presented for the purpose of study and estimates the fundamental electromagnetic properties of the bundle of single-walled carbon nanotubes with circular geometrical structure. The bundle of single-walled carbon nanotubes (SWCNTs) dipole antenna will be employed for this purpose by using Drude method at THz frequency range. The armchair-single-walled carbon nanotube (armchair- SWCNTs) will...
This paper aims to investigate the fundamental properties of single-walled carbon nanotubes bundles dipole antenna at THz frequency band by using Drude method. Due to their metallic conducting properties, the armchair-SWCNTs will be utilized in this work to configure the bundle of SWCNTs. The cross section of bundle that will be investigated in the current work can be in a rectangular geometry filled...
This work investigates the fundamental properties of armchair single-wall carbon nanotubes (armchair-SWCNTs) dipole antenna at THz band using Drude method. Due to their metallic conducting properties, the armchair SWCNTs will be utilized in this work. The radiation pattern, s11 parameters, phase velocity and antenna directivity are presented for this antenna. The results demonstrate that armchair-SWCNTs...
Nb-doped TiO2 thin films have been successfully prepared using liquid phase solution method. For the first time, Nb-doped sol-gel has been combined with commercially available TiO2 nanopowder (Degussa P25) for preparing Nb-doped TiO2 photoanode for DSSC application. EDX analysis confirms the presence of Nb in the thin films. Nb-doped TiO2 sample showed improvement in term of electrical resistivity...
The paper investigates the influence of different aluminum doping concentration on the photoresponse characteristics of doped ZnO thin films. Aluminum doped ZnO (AZO) thin films have been prepared by sol-gel dip-coating technique on glass substrates. 0.4M sol of AZO were prepared using monoethanolamine (MEA) as the stabilizer, zinc acetate dehydrate (Zn(CH3COO)2.2H2O) as the precursor, 2-methoxyethanol...
Zinc Oxide (ZnO) thin films were deposited on a glass substrate by sol-gel process dip-coating method. Zinc acetate dehydrate Zn(O2 CCH3)2(H2O)2 are used as a starting material while 2-methoxyethanol (C3H8O2) and monoethanolamine (MEA) are used as a solvent and stabilizer. The molar ratio of zinc acetate dihydrate to MEA is 1:1. The molarity of the solution and pre-heating temperature were kept constant...
