On the temperature dependence of the optical band gap in the material system of lithium niobate and lithium tantalate
Maximilian Henneke, Michael Ruesing, Nina A. Lange +13
Lithium niobate and lithium tantalate see widespread use in optics and electronics, and are increasingly used for cryogenic applications. Despite their broad deployment, their opti…

In-situ SHG microscopy investigation of the domain-wall-conductivity enhancement procedure in lithium niobate
Iuliia Kiseleva, Boris Koppitz, Elke Beyreuther +3
Conductive domain walls (CDWs) in the uniaxial ferroelectric lithium niobate (LiNbO, LN) have attracted a lot of interest as potential elements in 2D nanoelectronics, due to th…
