The mechanism that facilitates polarization reorientation in KH2PO4 (KDP) was investigated using operando single-crystal neutron diffraction. Diffraction data were measured from a KDP single crystal during the application of alternating electric fields and were then binned into 40 increments to enable field-dependent single-crystal structure refinements. The field-dependent structures... https://www.sofiatrophy.com/product-category/10-inch/
