Ab initio study of proton-exchanged LiNbO3(I): Structural, thermodynamic, dielectric, and optical properties

Lingyuan Gao, Robert B. Wexler, Ruixiang Fei +1

Using first principles calculations, we study the ground-state structure of bulk proton-exchanged lithium niobate, which is also called hydrogen niobate and is widely used in waveg…
