WebJul 26, 2024 · The existence of ferroelectricity in Bi 2 O 2 Se nanosheets is confirmed by dielectric measurements and piezoresponse force spectroscopy. The spontaneous orthorhombic distortion in the ultrathin nanosheets breaks the local inversion symmetry, thereby resulting in ferroelectricity.
WebOct 1, 1971 · In Bi2WO6, Bi3TiNbO9 and Bi4Ti3012, the bismuth oxide layer de- forms in the same way at the ferroelectric transition. In the prototype struc- ture, Bi is coordinated to four oxygens arranged in a flat tetragonal pyramid. All four oxygens are in the bismuth oxide layer and the tetragonal symmetry dictates four equal Bi-O bond lengths.
