Research Progress on Two-Dimensional Van der Waals Ferroelectric Materials

Abstract

This article reviews the application of two-dimensional ferroelectric materials in next-generation high-performance storage and neuromorphic computing, summarizing how electronic doping can enhance the coercive field of sliding ferroelectric materials, thereby improving the stability and anti-interference capability of data storage. However, this article also points out the performance trade-offs it brings, such as the decrease in polarization intensity and the deterioration of crystal quality. Research has found that by using mechanical probe imprinting technology combined with a flexible substrate, it is possible to achieve bidirectional, reversible, and non-destructive polarization switching in ultrathin ferroelectric films, solving the longstanding problem that traditional methods could only switch in one direction. On this basis, this paper discusses the engineering challenges that constrain its commercialization process, such as maintaining a high signal-to-noise ratio in the output while improving storage stability, and converting the inefficient point-by-point probe operations into large-area parallel production techniques compatible with mainstream semiconductor processes.
