Kimyasal Banyo Biriktirme Yöntemiyle Elde Edilen İğne Deliksiz PbS İnce Filmler

Abstract

Bu çalışmada, kimyasal banyo biriktirme yöntemi kullanılarak tek, iki ve üç katmanlı (Kurşun Sülfür) PbS ince filmler üretilmiştir. Literatür taramasında görüldüğü gibi, PbS ince filmlerin katman katman üretimi ilk kez gerçekleştirilmiştir. Kristal yapılarını araştırmak için X-ışını difraktometre (XRD) analizi kullanıldı. Yapısal analizler kristalit boyutunun tabaka sayısına bağlı olarak yaklaşık 40 nm'den 8-10 nm'ye düştüğünü göstermiştir. Filmlerin yüzey görüntüleri taramalı elektron mikroskobu (SEM) cihazı ile incelenmiştir. PbS filmi tek kat olarak elde edildiğinde numune yüzeyinde bazı çatlaklar, iğne delikleri ve boşluklar gözlenmiştir. Ancak filmler iki ve üç kat kaplandığında film yüzeyinde herhangi bir çatlak, boşluk veya iğne deliği oluşumu görülmedi.

Pinhole-Free PbS Thin Films Obtained by Chemical Bath Deposition Method

Abstract

In this study, the (Lead Sulfide) PbS thin films with one, two, and three layers were fabricated by employing the chemical bath deposition method. Layer by layer production of PbS thin films was realized for the first time as seen in the literature review. For investigating the crystal structures, the X-ray diffraction (XRD) analysis was used. The structural analyses indicated that the crystallite size was decreased from about 40 nm to 8-10 nm depending on the number of layers. The surface micrographs of the films were obtained using scanning electron microscopy (SEM). When the PbS film was obtained in one layer, some cracks, pinholes, and voids were observed on the sample surface. However, no cracks, voids, or pinhole formation were found on the film surface when the films were coated in two and three layers.
