in the present study, we investigate dc conduction mechanism of electron beam evaporated bromoaluminium phthalocyanine (bralpc) thin films using aluminum and gold electrodes. the current-voltage characteristics of sandwich type device are evaluated for the temperature range 298-413k under dark conditions. it is observed that the current passing through the device is increased by increasing te...
In this paper, the noise equivalent power (NEP) of an optical sensor based ongraphene-superconductor junctions in the constant current mode of operation has beencalculated. Furthermore, the necessary investigations to optimize the device noise withrespect to various parameters such as the operating temperature, magnetic field, deviceresistance, voltage and current bias have been presented. By s...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
با پیشرفت و همگانی شدن کامپیوترها، نیاز برای انتقال داده به کامپیوترها افزایش پیدا کرد. پورت ها وسیله ای برای ارتباط با device های جانبی متنوع از جمله کیبورد، میکروفون و ... هستند. با گذشت زمان پورتها به منظور پشتیبانی از گستره وسیعی از device ها، پیشرفته تر و کابردی تر شدند. با روی کار آمدن پورت usb دراواسط دهه 1990، این پورت توانست جایگزین سایر پورت های موجود شود چراکه این پورت ها به تنوع نا...
In the present work, the effects of different casting parameters including pouring temperature and cooling rate on stainless steel structures and mechanical properties of heat resistant alloy (HH) were studied. Mo nanoparticles were synthesized through sol-gel method and were coated on the stainless steel device using spin-coating method. The effect of coating layer on the device was studied by...
