Ultrafast switching and high-endurance nonvolatile memory enabled by intrinsic switchable polarization in semiconducting Janus monolayers

Ngoc Thanh Duong, Swathi Krishna, Minh Chien Nguyen, Hang Sik Kim et autres

The discovery of two-dimensional (2D) semiconducting ferroelectric (SFe) materials marks a pivotal step toward the realization of ferroelectric random-access memory. Despite their potential as ideal platforms for ultrafast switching and ultralow power consumption, SFe monolayers remain largely unexplored. In this work, we …
