The field of two-dimensional materials has seen enormous growth since the discovery of graphene, largely driven by the promise of exotic electronic properties that can be exploited in novel applications. Unfortunately many of the two-dimensional materials studied thus far exhibit either large band gaps or high mobilities but not both.Scientists at …

An international collaboration, including the University of Cambridge, has shown that quantum mechanical effects are central to the high temperature (up to 203K, -70 degrees Celsius) superconductivity that has been measured in hydrogen sulphide under extreme compression.Earlier results of the collaboration addressed the superconducting mechanism[1]…

Under normal conditions the noble gases, helium, neon and the heavier argon, krypton, xenon and radon, are unreactive. One of the enduring geochemical mysteries is the apparent lack of xenon in the Earth's crust and atmosphere. It has long been speculated that xenon might be locked up in compounds under extreme compression within the Earth - but li…
