Metal Magic: Creating Dream Materials with Semiconductor Quantum Dots
Science and Technology Daily, Beijing, May 30 (Reporter Zhang Jiaxin) According to the latest issue of Nature Communication, a team including researchers from Japan's RIKEN Emerging Materials Science Center has successfully created a "superlattice" composed of lead sulfide semiconductor colloidal quantum dots, in which researchers have realized the conductivity of similar metals, which is 1 million times higher than the current quantum dot displays, And it will not affect the quantum confinement effect. This progress may completely change quantum dot technology, enabling new applications in electroluminescent devices, lasers, thermoelectric devices, and sensors...
