Ferroelectric Polarization in an Elementary Substance or Single-Element Compound

A technical paper titled "Two-dimensional ferroelectricity in a single-element bismuth monolayer" was published by researchers at National University of Singapore, Zhejiang University, Tianjin University, and University of Chinese Academy of Sciences. Abstract "Ferroelectric materials are fascinating for their non-volatile switchable electric polarizations induced by the spontaneous inversi... » read more

Ferroelectric HEMT Reconfigurable Transistor (U. of Michigan)

A new technical paper titled "Fully epitaxial, monolithic ScAlN/AlGaN/GaN ferroelectric HEMT" was published by researchers at University of Michigan. “We can make our ferroelectric HEMT reconfigurable,” That means it can function as several devices, such as one amplifier working as several amplifiers that we can dynamically control. This allows us to reduce the circuit area and lower the... » read more

Antiferroelectric negative capacitance from a structural phase transition in zirconia

New research paper from 24-person research team from Berkeley, Georgia Tech, MIT, and other institutions. Abstract "Crystalline materials with broken inversion symmetry can exhibit a spontaneous electric polarization, which originates from a microscopic electric dipole moment. Long-range polar or anti-polar order of such permanent dipoles gives rise to ferroelectricity or antiferroelectrici... » read more

Interfacial ferroelectricity in marginally twisted 2D semiconductors

Abstract "Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of new metamaterials. Here we demonstrate a room temperature ferroelectric semiconductor that is assembled using mono- or few-layer MoS2. These van der Waals heterostructures feature broken inversion symmetry, which, together with the asymmetry of atomic arrangement at the interface of tw... » read more
