Background: Strontium titanate (SrTiO3, STO) has a typical perovskite structure
with unique physical and chemical properties, being widely used as a functional material in
electronic, piezoelectric and photocatalytic devices.
Method: Combining existing properties with high specific area and regular geometric
morphology to attain more accurate characteristics, nanoscale SrTiO3 has been generated.
Observation: This review introduces STO and doped nonstoichiometric STO nanomaterials,
especially barium strontium titanate (BST). Furthermore, nano-STO morphology control in
solvothermal synthesis and self-assembly in fabrication are discussed.
Result: The relevant applications such as in transistors and memory devices, thermoelectric
ceramics, and solar cells are also addressed.
