Abstract

Bu çalışmada ZnSe altlık üzerine “wet transfer” yöntemi kullanılarak aktarılan grafen filmlerin optik özellikleri incelenmiştir. Silisyum pul üzerine fiziksel buhar biriktirme (PVD) yöntemi kullanılarak nikel ince film kaplanmıştır. Kaplanan ince film üzerine kimyasal buhar biriktirme yöntemi (CVD) kullanılarak grafen büyütülmüştür. Büyütülen grafen ZnSe altlık üzerine transfer edilmiştir. Yapılan spektroskopik incelemeler neticesinde grafen filme ait sp3 melezleşmesi gözlenmiştir. Ayrıca, ZnSe altlık üzerine grafenin transfer edilmesiyle optik geçirgenlikte 10% civarında azalma tespit edilmiştir.
