Effect of substrate temperature on the properties of LiNbO3 nanocrystalline films during pulsed laser deposition
The results are presented from studying the effect substrate temperature has on the morphological, electrophysical, and optical parameters of LiNbO3 films obtained via pulsed laser deposition. It is established that films formed at temperatures of 300 to 600°C have a nanocrystalline structure with crystallites predominantly oriented in planes (110), (1010), and (220). The refractive index of the obtained films in the wavelength range of 500–800 nm varies from 2.13 to 2.26.
