Özet

Perovskit malzemeler pek çok uygulama için potansiyeli olan kristal malzemelerdir. Bu nedenle bu çalışmada temel prensip hesaplamalarına dayalı olarak TiPbO3 kübik perovskit kristalinin yapısal, elastik, elektronik ve optik özellikleri araştırılmıştır. Bu özellikleri belirlerken ABINIT programı kullanılmıştır. Hesaplamalar sonucunda TiPbO3 kristalinin örgü parametresi 7.6344 Bohr olarak belirlenmiştir. Ayrıca, TiPbO3 kübik perovskit kristalinin yarıiletken olduğu ve band aralığının 2.39 eV olduğu sonucuna ulaşılmıştır. TiPbO3 kristali için elastik özellikler araştırıldığında elastik sertlik sabitlerinden yola çıkarak elde edilen Poisson oranına bakarak kristalin esnek davranış sergilediği tahmin edilmektedir. Son olarak optik özellikleri incelenerek TiPbO3 kristalinin kompleks dielektrik fonksiyonu, kırılma indisi, soğurma katsayısı, sönüm katsayısı ve yansıtıcılığı hesaplanmıştır.

Abstract

Perovskite materials are crystalline materials with potential for many applications. Therefore, in this study, the structural, elastic, electronic and optical properties of TiPbO3 cubic perovskite crystal have been investigated based on calculations from first principles. ABINIT programme was used to determine these properties. As a result of the calculations, the lattice parameter of TiPbO3 crystal was determined as 7.6344 Bohr. It was also concluded that TiPbO3 cubic perovskite crystal is a semiconductor and its band gap is 2.39 eV. When the elastic properties are investigated for TiPbO3 crystal, it is estimated that the crystal exhibits flexible behaviour based on the Poisson ratio obtained from the elastic stiffness constants. Finally, the complex dielectric function, refractive index, absorption coefficient, extinction coefficient and reflectivity of TiPbO3 crystal were calculated by examining its optical properties.
