Journal Club: First observation of ‘superballistic’ electrons, flowing like a viscous fluid in graphene

Posted on September 8, 2017 by Stephen Ornes

Taking advantage of graphene’s special properties, physicists have experimentally observed a stream of record-breaking electrons that move with a conductance exceeding the limit theorists established decades ago. The researchers reported their findings recently in Nature Physics. For more than half … Continue reading →

Journal Club: A new, twisted topological insulator

Posted on April 24, 2017 by Stephen Ornes

About a decade ago, physicists began identifying and probing materials that suffer something of an identity crisis. On the surface of these crystals, electrons flow and form currents, like in a conductor. But in the interior, electrons are pinned and … Continue reading →
