Dielectric, spectral and Raman scattering studies of Nd-doped SrTiO3 single crystal

Improved separation efficiency of photogenerated carriers for Fe2O3/SrTiO3 heterojunction semiconductor

“…S2). The optical band gap value (E g ) could be obtained from the optical absorption spectra by using the relation, (ahn) 2 ¼ A(hn À E g ) for Fe 2 O 3 [23] and SrTiO 3 [24], where a is the absorption coefficient, hn is the photon energy, and A is a constant. The energy band gaps of the SrTiO 3 and Fe 2 O 3 can be estimated from a plot of (ahn) 2 versus photon energy hn.…”

Dielectric measurements, Raman scattering and surface studies of Sm-doped SrTiO3 single crystal

“…It consists mainly of the three scattering broad bands with maxima near 80 cm −1 , 300 cm −1 and 650 cm −1 [16,21,22]. Fig.…”

“…Influences of 4f-doping on STO single crystal properties are described in the literature [15,16]. However, research of properties of the SrTiO 3 doped by samarium is rarely found in the literature.…”

Characterization and dielectric properties of SrTi1−xMnxO3ceramics

“…6) Recently, there have been only a few reports with regard to the study of pure and TM-doped SrTiO 3 ceramics; 7) they concern mainly the dependence of their unique dielectric properties on the modified structure. 8) At room temperature, SrTiO 3 of a cubic crystal structure 9) exhibits a relatively high dielectric constant 10) and a greater resistance to high voltage. 11) From this point of view, there has been an increasing interest in SrTiO 3 ceramic in the application to capacitors in high-voltage conditions.…”
