[ 1 ] - A Study of ZnO Buffer Layer Effect on Physical Properties of ITO Thin Films Deposited on Different Substrates
The improvement of the physical properties of Indium Tin Oxide (ITO) layers is quite advantageous in photovoltaic applications. In this study the ITO film is deposited by RF sputtering onto p-type crystalline silicon (c-Si) with (100) orientation, multicrystalline silicon (mc-Si), and glass substrates coated with ZnO and annealed in vacuum furnace at 400°C. Electrical, optical, structural a...
[ 2 ] - Structural Properties of Post Annealed ITO Thin Films at Different Temperatures
Indium tin oxide (ITO) thin films were deposited on glass substrates by RF sputtering using an ITO ceramic target (In2O3-SnO2, 90-10 wt. %). After deposition, samples were annealed at different temperatures in vacuum furnace. The post vacuum annealing effects on the structural, optical and electrical properties of ITO films were investigated. Polycrystalline...
[ 3 ] - Ohmic Contact of Cu/Mo and Cu/Ti Thin Layers on Multi-Crystalline Silicon Substrates
Cu-Mo and Cu-Ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. Deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. The effects of process parameters such as film thickness, annealing duration and temp...
[ 4 ] - اثر زمان و دمای پارتیشن بندی در طول فرایند Q&P روی خواص مکانیکی فولاد 5142.1
محدودیت�ها روی مصرف سوخت و ایمنی در صنعت خودرو منجر به توسعه فولادهای استحکام بالای پیشرفته (AHSS) وبهبود استحکام و داکتیلیته شده است. به طوری که یکی از جدیدترین و امیدوارکننده ترین عملیات حرارتی ها برای توسعهAHSS، فرایند کوئنچ و پارتیشن بندی (Q&P) است. انجام این فرایند جدید در دماها و زمان های مختلف، منجر به ترکیب جالب توجهی از خواص مکانیکی شامل استحکام بالا همراه با داکتیلیته خوب می�شود. در ا...
