In this work, multi-layer thin films (insulator - metal - insulator) were prepared on glass substrates. Where we deposited the following order of (zinc oxide - silver - zinc oxide) by magnetron sputtering of zinc oxide and vacuum thermal evaporation technique for silver.
تم في هذا البحث دراسة تفاعل أكسيد البنزوفيورازان مع الأسيتون لتشكيل المركب2-متيل 1 , 4-ثنائي أكسيد الكينوكسالين باستخدام الحفز الضوئي من خلال اتباع منهجية علمية جديدة تعتمد على محاكاة التفاعل كوانتياً ومن ثم تطبيقه تجريبياً
In this paper samples of poly vinyl chloride PVC ,pure, irradiated
with Gama rays, were prepared by casting method in room
temperature and light, and under atmosphere pressure.
It was observed from this research that irradiation made real effect
on some of the studied optical properties, the irradiation increased
the transmittance while the electronic transitions kind remained
indirect before and after the irradiation.
In this paper we present the structural, optical and electrical characteristics of ZnO thin films grown for different parameters by the atomic layer deposition (ALD) method. The films were grown on glass and silicon substrates at low temperatures. We
used diethyl-zinc (DEZn) and deionized water as zinc and an oxygen sources, respectively. Measurements of surface morphology, photoluminescence at room temperature (RT PL) and Hall Effect were made for ZnO layers. The films obtained at 130°C show the highest carrier concentration (1.1×1019 cm-3) and the lowest resistivity (2.84×10-2 Wcm). The films exhibit mobility up to 19.98 cm2/Vs that we associate to the technological process used.
