Shallow trap modelling of infrared sensitive BaTiO3

Ross, G.W., Jeffrey, P.M., Eason, R.W., Damzen, M.J., Garcia, R.R., Troth, R., Garrett, M.H. and Rytz, D. (1994) Shallow trap modelling of infrared sensitive BaTiO3 At CLEO Europe: Conference on Lasers & Electro-Optics Europe, Netherlands. 28 Aug - 02 Sep 1994.

Record type: Conference or Workshop Item (Paper)


We present experimental data for the intensity-dependent absorption coefficient of a photorefractive "blue" sample of rhodium-doped BaTiO3 using beams of different wavelengths. A numerical photorefractive two-level model incorporating dual-wavelength illumination and a secondary photorefractive centre gives good agreement with experiment. We deduce values for the number densities, photoionisation cross-sections, thermal ionisation rate and recombination coefficients of the photorefractive centres. In this sample we determine that there is the usual deep trap concentration of ~ 2x10.
