Since the discovery of Rochelle salt a century ago, ferroelectric materials have been
investigated extensively due to their robust responses to electric, mechanical, thermal …

The investigation of two‐dimensional (2D) ferroelectrics has attracted significant interest in
recent years for applications in functional electronics. Without the limitation of a finite size …

Polar metals have recently garnered increasing interest because of their promising
functionalities. Here we report the experimental realization of an intrinsic coexisting …

Coexistence of reversible polar distortions and metallicity leading to a ferroelectric metal,
first suggested by Anderson and Blount in 1965, has so far remained elusive. Electrically …

The nature of superconductivity in SrTiO3, the first oxide superconductor to be discovered,
remains a subject of intense debate several decades after its discovery. SrTiO3 is also an …

Electronic transport in materials is governed by a series of tensorial properties such as
conductivity, Seebeck coefficient, and effective mass. These quantities are paramount to the …

We review the class of materials known as polar metals, in which polarity and metallicity
coexist in the same phase. While the notion of polar metals was first invoked more than 50 …

Recently, two-dimensional (2D) multiferroics have attracted a lot of attention due to their
fascinating properties and promising applications. Although the ferroelectric (FE)-ferroelastic …

The possibility of reconciliation between seemingly mutually exclusive properties in one
system can not only lead to theoretical breakthroughs but also potential novel applications …

Ferroelectricity, the electrostatic counterpart to ferromagnetism, has long been thought to be
incompatible with metallicity due to screening of electric dipoles and external electric fields …
