WebElectric field control of chirality. Sci. Adv. 8, eabj8030 (2024). Polar textures have attracted substantial attention in recent years as a promising analog to spin-based textures in ferromagnets. Here, using optical second-harmonic generation–based circular dichroism, we demonstrate deterministic and reversible control of chirality over ... WebJan 5, 2024 · Second, the application of an electric field induces larger offsets between the core of the vortices and, therefore, there is an enhancement of the helicity. Fig. 4.

WebAug 7, 2024 · Control of chirality was indicated from the proportionate response to a non-structurally distorting electric field. The bond-flexing was determined to be a measure of bond strain, which could be a factor of three lower or higher, depending on the direction of the electric field, than in the absence of the electric field. WebMay 28, 2024 · The microscopic origins of the chirality, the pathway during the switching, and the mechanism for electric-field control are described theoretically via phase-field … cyme user group meeting
