New research shows how Cooper pairs -- quasiparticles that make superconductivity possible -- can also play an opposite role in an exotic type of insulating materials known as Cooper pair insulators.
The quantum theory group at the University of Sydney is behind two papers published this month in Nature publications that are pushing the boundaries of quantum computing.
Drexel University researchers have developed a conductive ink made from a special type of material they discovered, called MXene, that was used by the Trinity College researchers to print components for electronic devices. The ink is additive-free, which means it can print the finished devices in one step without any special finishing treatments.
U.S. Naval Research Laboratory (NRL) discovers new method to passivate defects in next generation optical materials.
Researchers from Tokyo Metropolitan University have found that crystals of a recently discovered superconducting material, a layered bismuth chalcogenide with a four-fold symmetric structure, shows only two-fold symmetry in its superconductivity. The origin of superconductivity in these structures is not yet well understood; this finding suggests a connection with an enigmatic class of materials known as nematic superconductors and the extraordinary mechanisms by which superconductivity can emerge at easier-to-reach temperatures.
Gold atoms ski along boron nitride nanotubes and stabilize in metallic monolayers. The resulting gold quantum dots could be a promising material for future electronics and quantum computing.
Tiny, individual, flexible ribbons of crystalline phosphorus have been made by UCL researchers in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene, which is the phosphorus equivalent of graphene, in 2014, more than 100 theoretical studies have predicted that new and exciting properties could emerge by producing narrow 'ribbons' of this material. These properties could be extremely valuable to a range of industries.
UT Austin engineers have developed a tool to provide quantitative feedback on material quality, with particular applications in optoelectronic devices.
Russian physicist Viktor Lakhno from Keldysh Institute of Applied Mathematics, RAS considers symmetrical bipolarons as a basis of high-temperature superconductivity. The theory explains recent experiments in which a superconductivity was reached in lanthanum hydride LaH10 at extra-high pressure at nearly room temperature. The results of the study are published in Physica C: Superconductivity and its Applications.
In a collaboration between the US Department of Energy's Ames Laboratory and Northeastern University, scientists have developed a model for predicting the shape of metal nanocrystals or 'islands' sandwiched between or below two-dimensional (2D) materials such as graphene. The advance moves 2D quantum materials a step closer to applications in electronics.
