Barium Strontium Titaanate Thin Film Analysis | NIST
Abstract Barium Strontium Titanate (BST) is under consideration as a high dielectric constant material for a number of semiconductor applications. Because of its very large dielectric constant, BST is seen as an enabling material that will allow the continual shrinking of integrated circuits and progression along the path of Moore's Law.

Strontium titanate | Cerámica Wiki | Fandom
Strontium titanate is an oxide of strontium and titanium with the chemical formula SrTiO3. It is a centrosymmetric ferroelectric material with a perovskite structure. It was long thought to be a wholly artificial material, until 1982 when its natural counterpart—discovered in Siberia and named tausonite—was recognised by the IMA. Tausonite remains an extremely rare mineral in nature ...
