Optical study and simulation of diffusion of copper ions in the linbo3 crystal
The article deals with research into the processes of diffusion and drift of copper ions in a lithium niobate crystal after annealing in the presence of a copper film deposited on the crystal surface. For this purpose, there are chosen temperatures T = 600, 650, 700, 750 and 800°C, with the duration of high-temperature annealing being 6 hours for each sample.
