Fabrication and characterization of 50 nm silicon nano-gap structures
T.S, Dhahi; Uda, Hashim, Prof. Dr.; N.M., Ahmed (American Scientific Publishers, 2011-04)A simple method for the fabrication of nano-gaps less than 50 nm by using conventional photolithography combined with patterned-size reduction techniques is presented. Silicon material is used to fabricate the nano-gap ... -
Fabrication and characterization of gold nano-gaps for ssDNA immobilization and hybridization detection
T.S., Dhahi; Uda, Hashim, Prof. Dr.; N.M., Ahmed; H., Nazma (Journal of New Materials for Electrochemical Systems, 2011)We develop a method for fabricating the nano-gaps directly by using just photolithography and wet etching processes without any nano lithography or difficult techniques. It shows that this resolution enhancement allows one ... -
Investigated optical and elastic properties of Porous silicon: Theoretical study
Y., Al-Douri; N.M., Ahmed; N., Bouarissa; A, Bouhemadou (Elsevier Ltd., 2011-08)Compatibility between experimental and theoretical works is achieved. Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical ...
