The brakes in this case are an electron energy density wave – fixed electrons that inhibit free-flying electrons, according to the US Brookhaven National Laboratory. “Many researchers believe that the ...

In their quest to explore and characterize high-temperature superconductors, physicists have mostly focused on a material that is not the absolute highest. That's because that crystal is much easier ...

(Phys.org)—A team of researchers with members from several countries in Europe has used a type of X-ray diffraction to reveal defects in the way a superconductor develops. In their paper published in ...

Copper oxide-based superconductors were discovered in 1986. Known as cuprate or high-T c (for “high critical temperature”) superconductors, these materials have a much higher temperature for the ...

Despite being vital to the study of superconductivity in cuprate materials the physical origins of the pseudogap remain a mystery. Over three decades since the discovery of high-temperature ...

The discovery of superconductivity in cuprates, a class of ceramic materials, in 1986 has boosted an impressive effort of research all around the world. These materials still hold the record for the ...

Scanning tunneling microscopy was used to analyze a cuprate high-temperature superconductor modified into an insulating state by a team of researchers from Boston College and Brookhaven National ...

Numerous symmetry-breaking electronic states have been theoretically proposed to explain the cuprate pseudogap. A two-dimensional ‘checkerboard’ charge density wave (CDW), may break translational but ...

This study is led by Dr. Lu Jiong from National University of Singapore (NUS), in collaboration with Dr. Koh Ming Joo (NUS), Dr Chun Zhang (NUS) and Dr. Honghan Fei from (Tongji University). This team ...

The new method of doping allowed the team to change the oxygen content of the superconductor over a much wider range than was previously possible, and even to switch it from being hole-doped to ...
