摘要：
Iron-doped X-cut lithium niobate crystals were prepared by means of thermal diffusion from thin film varying in a systematic way the process parameters such as temperature and diffusion duration. Secondary Ion Mass Spectrometry was exploited to characterize the iron in-depth profiles. The evolution of the composition of the Fe thin film in the range between 600A degrees C and 800A degrees C was studied, and the diffusion coefficient at different temperatures in the range between 900A degrees C and 1050A degrees C and the activation energy of the diffusion process were estimated.
