Computer simulation of metal co-doping in lithium niobate (2014)
Journal Article
Araujo, R. M., Valerio, M. E. G., & Jackson, R. A. (2014). Computer simulation of metal co-doping in lithium niobate. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 470(2171), Article 20140406. https://doi.org/10.1098/rspa.2014.0406

Lithium niobate, LiNbO3, is an important technological material with good electro-optic, acousto-optic, elasto-optic, piezoelectric and nonlinear properties. Computer modelling provides a useful means of determining the properties of the material, in... Read More about Computer simulation of metal co-doping in lithium niobate.

Tantalum and niobium diffusion in single crystalline lithium niobate (2014)
Journal Article
Fielitz, P., Borchardt, G., Ganschow, S., Bertram, R., Jackson, R., Fritze, H., & Becker, K. (2014). Tantalum and niobium diffusion in single crystalline lithium niobate. Solid State Ionics, 259, 14-20. https://doi.org/10.1016/j.ssi.2014.02.005

LiNbO3 and LiTaO3 are isomorphous and Nb and Ta have the same valence electron configuration and the same ionic radii. This suggests the use of Ta as a tracer to probe the self-diffusion of Nb in LiNbO3. The diffusion system consisted of a 20 nm laye...

229Thorium-doped calcium fluoride for nuclear laser spectroscopy. (2014)
Journal Article
Jackson. (2014). 229Thorium-doped calcium fluoride for nuclear laser spectroscopy. Journal of Physics: Condensed Matter, 105402 -105402. https://doi.org/10.1088/0953-8984/26/10/105402

The (229)thorium isotope presents an extremely low-energy isomer state of the nucleus which is expected around 7.8 eV, in the vacuum ultraviolet (VUV) regime. This unique system may bridge between atomic and nuclear physics, enabling coherent manipul... Read More about 229Thorium-doped calcium fluoride for nuclear laser spectroscopy..

Preparation of high-purity LiF, YF3, and YbF3for laser refrigeration (2014)
Journal Article
Hehlen, M. P., Boncher, W. L., Melgaard, S. D., Blair, M. W., Jackson, R. A., Littleford, T. E., & Love, S. P. (2014). Preparation of high-purity LiF, YF3, and YbF3for laser refrigeration. Proceedings of SPIE, https://doi.org/10.1117/12.2039547

The role of transition-metal impurities in Yb3+-doped YLiF4 (YLF) laser-cooling crystals is studied. Divalent 3d transition-metal ions, in particular Fe2+, are found to have strong absorptions at the laser cooling pump wavelength and degrade the cool...

Derivation of enhanced potentials for plutonium dioxide and the calculation of lattice and intrinsic defect properties (2014)
Journal Article
Read, M. S., Walker, S. R., & Jackson, R. A. (2014). Derivation of enhanced potentials for plutonium dioxide and the calculation of lattice and intrinsic defect properties. Journal of Nuclear Materials, 448(1-3), 20-25. https://doi.org/10.1016/j.jnucmat.2014.01.020

A new potential has been derived for plutonium dioxide and used to calculate its lattice and defect properties. The Pu4+ ⋯ O2− potential is obtained via a combination of empirical fitting to crystal structural data and parametric fitting to additiona...
