New paper published in Phys. Rev. B. on Vibrational modes and overlap matrix of LiNb1-xTaxO3 mixed crystals.
In collaboration with Oxford University a reproducible and low-cost method of modifying the optical properties of crystalline Lithium Tantalate enables highly accurate temperature readings, down to individual milli-kelvins, over a broad range of temperatures: -120°C to +680°C. More details here.
Selected images of optical birefringence recorded during heating of dodecasil-3C crystals from our collaboration with Richard Walton's group chosen to be the 2011 Journal of Applied Crystallography cover image.
