## Title

- title: Optical Detection of Sliding Ferroelectric Switching in hBN with a WSe<sub>2</sub>
    Monolayer
  title_type: original
  lang: en

## Description

- description: When two BN layers are stacked in parallel in an AB or BA arrangement,
    a spontaneous out-of-plane electric polarization arises due to charge transfer
    in the out-of-plane B–N bonds. The ferroelectric switching from AB to BA (or BA
    to AB) can be achieved with a relatively small out-of-plane electric field through
    the in-plane sliding of one atomic layer over the other. However, the optical
    detection of such ferroelectric switching in hBN has not yet been demonstrated.
    In this study, we utilize an adjacent WSe2 monolayer to detect the ferroelectric
    switching in BN. This dynamic coupling between a two-dimensional (2D) ferroelectric
    and a 2D semiconductor allows for the fundamental investigation of the ferroelectric
    material using a nondestructive, local optical probe, offering promising applications
    for compact and nonvolatile memory devices.
