Executive Summary : | Ferroelectric materials, such as graphene and 2D semiconductors, have potential applications in electronics, energy storage, and optoelectronics. However, when reduced to thin layers, they lose their ferroelectric properties due to the dominant depolarization field. Recent discoveries show that 2D ferroelectrics can minimize this depolarization field through intralayer displacement and lattice distortion. Light irradiation can control ferroelectricity, offering non-contact manipulation, low power consumption, and control over multiple parameters in optoelectronic devices. To address this challenge, a single layer of graphene can be used as an electrode to reversibly control the imprint and screening fields. This approach can be used for applications such as tunnel field effect transistors, photodetectors, neuromorphic computing, and logic circuits. |
