Calligraphic poling of Lithium Niobate
Optics Express, 2005 We demonstrate a novel technique for instituting complex and arbitrary shaped micron-scale domain patterns in LiNbO3 at room temperature. Fabrication of continuous domains as narrow as 2 microm across and hexagonal patterns of the same order accompanied by real time visualization of the poling process are presented.

Self-Diffusion of Lithium in Amorphous Lithium Niobate Layers [PDF]
Zeitschrift für Physikalische Chemie, 2012 Abstract We investigated lithium self-diffusion in amorphous lithium niobate layers between 298 and 423 K. For the experiments, amorphous 6LiNbO3/ 7LiNbO3 isotope hetero-structures were deposited by ion beam sputtering and analysed after diffusion annealing by secondary ion mass spectrometry (SIMS).
