Relationship between the dielectric constant and corresponding defect concentration of lithium niobate crystals is studied. An ion polarizability additivity rule of dielectric constants of complex substances and the Li-site vacancy model are employed in the present work. The obtained linear correlation betwe...
Lithium niobate (LiNbO 3 ) on insulator (LNOI) is a promising material platform for integrated photonics due to single crystal LiNbO 3 film’s wide transparent window, high refractive index, and high second-order nonlinearity. Based on LNOI, the fast-dev
It could be seen that crystal growth is not classical, it takes place by nuclei coalescence within the clusters.The measured values of dielectric constant and refractive index, at a frequency of 1 kHz and at room temperature, are between those of the noncrystallized parent glass and the pure ...
Using a first-principles approach based on density-functional theory, the electronic, dielectric, and dynamical properties of the two phases of lithium niobate are studied. In particular, the spontaneous polarization, the optical dielectric tensors, the Born effective charges, and the zone-center pho...
