Witryna27 wrz 2024 · The organic ferroelectric material P(VDF-TrFE) was also used to modulate the ZnO film photodetector. Our results demonstrated that ferroelectric tuning can reduce the dark current and therefore the device power, which provides a new insight for high-performance UV photodetectors.
Witryna14 lip 2016 · Organic cocrystals are crystalline, single-phase materials composed of two or more molecular and/or ionic compounds, generally, in a stoichiometric ratio. A feature of organic cocrystals is that special optoelectronic properties such as ferroelectricity are easy to realize in these materials. In this perspective, we systematically introduce the … Witryna8 mar 2024 · For a long time, homochirality in ferroelectrics has been studied rarely, although the first ferroelectric Rochelle salt (potassium sodium l-tartrate tetrahydrate) discovered in 1920 is a homochiral one …
