4 Jan 2023 | Abstract: | Antiferroelectric (AFE) materials have received tremendous attention owing to
their high energy conversion efficiency and good tunability. Recently, an
exotic two-dimensional (2D) AFE material,
$eta’-mathrm{In}_{2}mathrm{Se}_{3}$ monolayer that could host atomically
thin AFE nanostripe domains has been experimentally synthesized and
theoretically examined. In this work, we apply first-principles calculations
and theoretical estimations to predict that light irradiation can control the
nanostripe width of such a system. We suggest that an intermediate
near-infrared light (below bandgap) could effectively harness the thermodynamic
Gibbs free energy, and the AFE nanostripe width will gradually reduce. We also
propose to use an above bandgap linearly polarized light to generate AFE
nanostripespecific photocurrent, providing an all-optical pump-probe setup for
such AFE nanostripe width phase transitions. | Source: | arXiv, 2301.01425 | Services: | Forum | Review | PDF | Favorites |
