Abstract

Bu çalışmada hidrotermal yöntem kullanılarak Çinko Oksit (ZnO) nanoparçacık sentezlendi. Sentezlenen ZnO nanoparçacık geçirimli elektron mikroskobu ve x-ışınları ile karakterizasyonu yapıldı. ZnO nanoparçacık, E7 nematik sıvı kristaline farklı oranlarda katkılanarak numuneler elde edildi. Bu numunelerin gerçek ve sanal dielektrik sabiti ve mutlak kapasitans değişimleri 100 Hz-15 MHz frekans aralığında oda sıcaklığında incelenmiştir. Gerçek dielektrik belli frekansa kadar sabit gibi çok az azalarak değiştiği, 0.8 MHz frekansa gelince birden bire azalarak sıfır olduğu, nanoparçacık katkı oran ile arttığı tespit edilmiştir. Sanal dielektrik kısmı düşük frekanslarda azalmakta, sonra sabit gibi davranıyor ve daha yüksek frekansta artarak yaklaşık 2 MHz frekans civarında pik yapar ve azalarak sıfıra gidiyor. Sıvı kristalin dielektrik ve kapasitans değerleri % 0.6 ZnO nanoparçacık katkı oranında en büyük değişim göstermektedir.
