In-plane Ferroelectricity and Enhanced Piezoelectricity in Ultrathin AlN (1010) Surfaces

MNMohammad Noor-A-Alam

Key Points

  • This research explores the in-plane ferroelectric and piezoelectric properties of ultrathin w-AlN films.
  • Utilized density functional theory to model ultrathin w-AlN films.
  • Analyzed films composed of 2–5 layers of w-AlN.
  • Investigated surface properties of these structures.
  • Identified significant in-plane ferroelectricity in few-layer w-AlN films.
  • Enhanced piezoelectric properties observed with increasing layers of w-AlN.
  • Results suggest promising applications in nanotechnology and electronic devices.

Abstract

Using density functional theory, we investigate the in-plane ferroelectricity and piezoelectricity of the w-AlN (1010) surface in ultrathin films composed of 2--5 w-AlN layers. We find that these few-layer structures. . .
