WebApr 26, 2024 · Indeed, conventional ferroelectric memories are based on perovskites materials, mostly the lead zirconate titanate (PZT), which presents major challenges related to a rather complicated crystal structure, high-processing temperatures, and the difficulty to scale down the ferroelectric layer thickness below 70–100 nm. 3,4 3. K. WebJul 22, 2016 · The incipient ferroelectric behaviour of IV–VI compounds is strongly sensitive to carrier concentration 23, which suggests the importance of the valence and conduction p-type bands very near the band edges in determining the equilibrium structure 1.

WebThe coexistence and competition between superconductivity and electronic orders, such as spin or charge density waves, have been a central issue in high transition-temperature (T c) superconductors.Unlike other iron-based superconductors, FeSe exhibits nematic ordering without magnetism whose relationship with its superconductivity remains unclear. WebQuantum paraelectricity is a type of incipient ferroelectricity where the onset of ferroelectric order is suppressed by quantum fluctuations. From the soft mode theory of ferroelectricity, this occurs when a ferroelectric instability is stabilized by quantum fluctuations.In this case the soft-mode frequency never becomes unstable (Fig. 1a) as …
