They fabricated a special crystal structure called a superlattice from alternating layers of lead titanate (an electrically polar material, whereby one end is positively charged and the opposite end is negatively charged) and strontium titanate (an insulator, or a material that doesn't conduct electric current).
On the other hand, although early research has showed that the Barium Strontium Titanate (BST) dielectric has the property to modify its dielectric constant by applying different electric field levels, recent research have shown that this property could be used to develop voltage-controlled capacitors, which in turn, can be used to improve the performances of the oscillators [15-17].
Strontium titanate powders were synthesized via hydrothermal route [21] using strontium hydroxide (99%, Alfa Aesar) and titanium tetrachloride (99.9%, Fisher Scientific) as precursor materials.
Another basic compound is strontium titanate SrTi[O.sub.3] (denoted as ST), a paraelectric material containing the cubic phase at room temperature.
Strontium titanate (STO) and neodymium titanate (NTO) are oxides.
