Conductivity and photoconductivity mechanisms of iron and magnesium doped lithium niobate

Author

Joseph Francis Kirchhoff

Abstract

Various compositions of lithium niobate crystals were observed to have an electrical conductivity given by 2.3 x 10³ exp(-1.21/kT) Ω^-1 m^-1 between 200 and 3 15°C. This implies that in this temperature range, all such crystals exhibit comparable carrier concentration and mobility. A model based on intrinsic conductivity is presented which adequately agrees with experiment. In addition, a model is presented by which electronic photoconductivity can be predicted by evaluating the trapping cross-section associated with Fe³⁺ ions dependent upon their lattice sites"-- Abstract, p. ii
