TLDR
A resonant operation mode of a new adaptive bending X-Ray optics (ABXO) element based on bidomain LiNbO3 single crystal piezoactuator is studied and described in this paper.Abstract:
A resonant operation mode of a new adaptive bending X-Ray optics (ABXO) element based on bidomain LiNbO3 single crystal piezoactuator is studied and described. Spatial and temporal parameters of X-Ray beam tuning by this element are investigated. Experimental measurements and numerical calculations have been performed for the element functional characteristics: oscillatory spectrum, speed of angular adjustment, angular range of scanning. For the first time, the application of the ABXO element has been tested at a source of synchrotron radiation for controlling the X-Ray beam parameters in time-resolved X-Ray diffraction experiments.read more

TL;DR: In this paper, the authors focused on flat and almost completely charged domain walls (CDWs) of large area in undoped bidomain LN crystals heat-treated in a reducing atmosphere, and revealed that the electrical conductivity of head-to-head CDWs in the reduced LN (RLN) is accessible without super-bandgap photoexcitation, shows memristive behavior and can be tuned by applying an external voltage, while tail-totail CDWs are insulating.

TL;DR: A small discrepancy between the theory and the experimental data has been discovered in cases where the incident beam is sufficiently collimated and monochromated, which indicates the presence of a certain number of lattice defects in the sample under study.
