For the first time, researchers isolated and characterized atomically thin 2-D crystals of pentagons bonded together in palladium diselenide (PdSe2). The research confirmed predictions that the puckered structure would be stable.
The unique structure of the material results in beneficial properties. It has fast-moving electrons. Also, it is stable in air. Other 2-D semiconductors are not stable in air. These properties may enable advanced uses in detectors, solar cells, and transistors. Further, this material could advance superconductivity for electrical flow without losses, piezoelectric sensors, and energy-efficient computing.
