[ 1 ] - بررسی تغییرات پارامترهای ساختاری نانوسیم‌های مغناطیسی نیکل بر بازده الکترونهشت
In this work, magnetic Ni nanowire arrays were ac-pulse electrodeposited into the anodic aluminum oxide (AAO) template fabricated by the common two-step anodization technique. The barrier layers at the bottom of the pores were exponentially thinned in a non-equilibrium anodization process to 8, 12, 16 and 20 V. These were fabricated using the constant of 15 mA deposition current, 48 mS off-tim...
[ 2 ] - تأثیر لایه‌های مختلف اکسید بر خواص حسگری فیلم آلومینای آندی نانوحفره‌دار
In the present work, anodized aluminum oxide template was prepared by accelerated mild anodization technique in 0.6M phosphoric aside and 175 V, anodization voltage. Pore widening was performed by chemical etching in 0.5M phosphoric acid for 8, 16, 32, 40 minutes. Scanning Electron Microscopy (SEM) images showed the pores, diameter exponentially increases with etching time. By depositing silver...
[ 3 ] - تعیین تابع توزیع بهینه نمار شکست و عمق نفوذ آنیونها در بلور نوری آلومینای حفره‌دار
Band structure of porous alumina photonic crystal in the Γ X direction was calculated using order-N method . In a comparison of calculated results with experimental data of reflective and absorptive index, the variation of refractive index of alumina in the external region of oxide layer, around the pores were studied. A Gaussian distribution function was adopted for phosphate anions in the e...
