Features and Benefits

loss tangent at 10 GHz = ~5 × 10-4 (300 K), ~3 × 10-4 (77 K)
Single crystal strontium titanate substrate lattice has a good lattice match with most perovskite structured materials. It is an excellent substrate from the epitaxial growth of many oxide this films and high-temperature superconductors. It also has applications in optical windows and as a high-quality sputtering target.

The transport properties of ultra-thin SrTiO(3) (STO) layers grown over YBa(2)Cu(3)O(7) electrodes were studied by conductive atomic force microscopy at the nano-scale. A very good control of the barrier thickness was achieved during the deposition process. A phenomenological approach was...

Novel PMMA-STO-CNT matrices were created by opened-tip vertically aligned multiwalled carbon nanotubes (VA-MWCNTs) with conformal coatings of strontium titanate (STO) and poly(methyl methacrylate) (PMMA). Emission threshold of 0.8 V/μm was demonstrated, about 5-fold lower than that of the as-grown VA-MWCNTs....

SrTiO(3) (STO) is a large band gap (3.2 eV) semiconductor that catalyzes the overall water splitting reaction under UV light irradiation in the presence of a NiO cocatalyst. As we show here, the reactivity persists in nanoscale particles of the...
