About

The Iraqi Journal of Applied Physics (IJAP) is a peer reviewed journal of high quality devoted to the publication of original research papers from applied physics and their broad range of applications. IJAP publishes quality original research papers, comprehensive review articles, survey articles, book reviews, dissertation abstracts in physics and its applications in the broadest sense. It is intended that the journal may act as an interdisciplinary forum for Physics and its applications. Innovative applications and material that brings together diverse areas of Physics are particularly welcome. Review articles in selected areas are published from time to time. It aims to disseminate knowledge; provide a learned reference in the field; and establish channels of communication between academic and research experts, policy makers and executives in industry, commerce and investment institutions. IJAP is a quarterly specialized periodical dedicated to publishing original papers, letters and reviews in: Applied & Nonlinear Optics, Applied Mechanics & Thermodynamics, Digital & Optical Communications, Electronic Materials & Devices, Laser Physics & Applications, Plasma Physics & Applications, Quantum Physics & Spectroscopy, Semiconductors & Optoelectronics, Solid State Physics & Applications, Alternative and Renewable Energy, Computers Networks and Applications.

Abstract

A study of nanostructural, optical and electrical characteristics of obliquely deposited thin sulfur-doped films is presented. The aim was to develop a wideband (0.6-11) micron laser detector operating at room temperature with no need to biasing or amplification. The deposition angle had a decisive role on the detector specifications, namely its detectivity and response time. At deposition angle of 70 deg, the maximum detectivity was achieved 3x10^9 W-1.Hz1/2.cm while at 60 deg a fastest response 1 microsecond was obtained.

Abstract

To grow InGaSb with larger In composition, step growth process was adapted. By increasing the In composition step by step, In0.1Ga0.9Sb single crystal of length 18 mm was grown. Intensities and the FWHM values of X-ray diffraction spectrum were, respectively, 10 times larger and one third of the value, compared with the values of the crystal grown directly from GaSb seed crystal.

Abstract

A computational investigation has been carried out in the field of nonrelativistic charged-particle optics using the charge density method as a boundary value problem with the aid of a personal computer under the absence of space-charge effects. This work has been concentrated on designing a two-electrode electrostatic immersion lens whose electrodes are cylindrical in shape separated by an air gap. The variable parameters of the two electrodes are the applied voltage ratio and the air gap separating them. The axial potential distribution of an electrostatic immersion lens has been computed by taking into consideration the distribution of the charge density due to the voltages applied on the two cylindrical electrodes. Potentials have been determined anywhere in space by using Coulomb’s law. The optical properties of the immersion lens have been investigated under finite and zero magnification conditions.
