A team of researchers affiliated with a host of institutions in Japan and one in the U.K has observed Fermi pockets during experiments with a five-layered cuprate, confirming theories. In their paper published in the journal ...
Ever smaller and ever more compact—this is the direction in which computer chips are developing, driven by industry. This is why so-called 2-D materials are considered to be the great hope: they are as thin as a material ...
