“…The modulation of the Fermi level and carrier density could be realized through the periodic external electric field induced by the polarized-up and down domains. 235 Jin et al reported the design of ferroelectric-gated nanoplasmonic devices based on graphene sheets clamped in ferroelectric crystals. 299 They proposed that there exists strong coupling between the two-dimensional plasmons in graphene with the phonon-polaritons in ferroelectrics, resulting in characteristic modal wavelengths of 100−200 nm at low temperature and low-THz frequencies.…”

In recent years, there has been growing interest in functional devices based on two-dimensional (2D) materials, which possess exotic physical properties. With an ultrathin thickness, the optoelectrical and electrical properties of 2D materials can be effectively tuned by an external field, which has stimulated considerable scientific activities. Ferroelectric fields with a nonvolatile and electrically switchable feature have exhibited enormous potential in controlling the electronic and optoelectronic properties of 2D materials, leading to an extremely fertile area of research. Here, we review the 2D materials and relevant devices integrated with ferroelectricity. This review starts to introduce the background about the concerned themes, namely 2D materials and ferroelectrics, and then presents the fundamental mechanisms, tuning strategies, as well as recent progress of the ferroelectric effect on the optical and electrical properties of 2D materials. Subsequently, the latest developments of 2D material-based electronic and optoelectronic devices integrated with ferroelectricity are summarized. Finally, the future outlook and challenges of this exciting field are suggested.

“…An ultrahigh responsivity up to 7.62 × 10 6 A W –1 has been reported in graphene-ferroelectrics photodetectors, which is much beyond the previously reported experimental results. Meanwhile, detectivity reached ∼6.24 × 10 7 Jones with an infrared band photodetection . Graphene was transferred on the prepolarized ferroelectric substrate, and the graphene plasmons were excited by the polarized domains.…”

Photodetectors are one of the most important components for a future “Internet-of-Things” information society. Compared to the mainstream semiconductor-based photodetectors, emerging devices based on two-dimensional (2D) materials and ferroelectrics as well as their hybrid systems have been extensively studied in recent decades due to their outstanding performances and related interesting physical, electrical, and optoelectronic phenomena. In this paper, we review the photodetection based on 2D materials and ferroelectric hybrid systems. The fundamentals of 2D and ferroelectric materials as well as the interaction in the hybrid system will be introduced. Ferroelectricity modulated optoelectronic properties in the hybrid system will be discussed in detail. After the basics and figures of merit of photodetectors are summarized, the 2D-ferroelectrics devices with different structures including p-n diodes, Schottky diodes, and field-effect transistors will be reviewed and compared. The polarization of ferroelectrics offers the possibility of the modulation and enhancement of the photodetection in the hybrid detectors, which will be discussed in depth. Finally, the challenges and perspectives of the photodetectors based on 2D ferroelectrics will be proposed. This Review outlines the important aspects of the recent development of the hybrid system of 2D and ferroelectric materials, which could interact with each other and thus lead to photodetectors with higher performances. Such a Review will be helpful for the research of emerging physical phenomena and for the design of multifunctional nanoscale electronic and optoelectronic devices.

“…Another method is to place a graphene layer on a periodically poled ferroelectric substrate, which has been shown via simulations to create a structured Fermi-level profile within the graphene due to electrostatic interactions with the substrates, and is capable of sustaining plasmonic resonances. [34][35][36][37][38] This method of using ferroelectric substrates has made modest progress experimentally, as spatially resolved Raman spectroscopy of graphene on poled lithium niobate has been shown to introduce a periodic variation in the graphene Fermi level [39] ; however, plasmonic resonances were not demonstrated. Reconfigurable tuning of 2D materials can be achieved by rewriting ferroelectric domains with an atomic force microscopy (AFM) tip, however, this is a slow process and limited to small areas.…”

Graphene plasmonic devices have been demonstrated to show great potential for reconfigurable metasurfaces due to the tuneable electronic charge transport properties of graphene in response to electrostatic gating. Iron‐doped lithium niobate is proposed as a platform for patterning‐free optically reconfigurable graphene metasurfaces in the THz spectral region. Under structured illumination, the lithium niobate undergoes charge migration in the bulk, where carriers migrate away from illuminated regions, forming spatially patterned charge distributions capable of electrostatic tuning of graphene. These charge distributions are stable in the dark, however, can be redefined by subsequent illumination. Through the use of numerical simulations, it is demonstrated that optically defined charge distributions in lithium niobate can tune locally the graphene Fermi level allowing for plasmonic resonances at THz frequencies.
