Abstract
An array of titanium (Ti) doped HfO2 [(Hf1-xTixO2) (x = 0.0–1.0)] nanoparticles (NPs) synthesis and the study of their structural, spectroscopic, and dielectric properties is reported. The Hf1-xTixO2 NPs were synthesized by a sol-gel type wet chemical process. The crystal structure of pure HfO2 and TiO2 NPs revealed by structural analysis is monoclinic (m) and tetragonal (t), respectively. The crystallinity of the doped samples was found to be dopant concentration-dependent. The microstructure of the obtained NPs was investigated along with their spectroscopic and dielectric characteristics. The tunable dielectric properties of Hf1-xTixO2 NPs make them ideal for high frequency, high-k applications.
