Refractive index strontium titanate
WebPhotorefractive crystals such as lithium niobate, barium titanate and strontium barium titanate, were used previously in holographic systems. In the last decades, a new class of … SrTiO3 has an indirect band gap of 3.25 eV and a direct gap of 3.75 eV in the typical range of semiconductors. Synthetic strontium titanate has a very large dielectric constant (300) at room temperature and low electric field. It has a specific resistivity of over 10 Ω-cm for very pure crystals. It is also used in high-voltage capacitors. Introducing mobile charge carriers by doping leads to Ferm…
