ABSTRACT

Strontium titanate (SrTiO₃) has excellent electrical and optical characteristics, which have made it a very popular material in high-k capacitors, oxygen sensors, superconducting materials, photocatalysts, and resistive random access memory (RRAM). This paper provides a review of the preparation and application research of SrTiO₃ and the doped single crystals with a systematic analysis of the common preparation paths which include solid-phase, sol-gel and single crystal growth. The solid-phase technique has advantages of ease and scalability, whereas the sol-gel technique permits to refine the grain and achieve compositional uniformity. Moreover, doping with elements like La⁺, Nb5⁺, Fe⁺, Co²⁺ and Mn⁺ can efficiently be used to manipulate its band structure. The experimental observations indicate that as the sintering temperature rises the crystallinity of the sample is rising and the grain size is growing as at 800degC and 1100degC, the thickness of the grain is 75 nm and 180 nm, respectively. Doped SrTiO₃ has a smaller bandgap and a higher photocatalytic performance, and its wide application opportunities in the environmental cleanup and photocatalytic systems, optoelectronics, and energy conversion are evident.
