A New Route to Nanoscale Conducting Channels in Insulating OxidesTwo-dimensional electron gases (2DEGs)—narrow conducting channels at the
surfaces and interfaces of semiconductor materials—are the bedrock of
conventional electronics. The startling 2004 discovery that such 2DEGs

Two Phase Transitions Make a High-Temperature SuperconductorSuperconductivity—conceptually remarkable and practically revolutionary—is a quantum phenomenon in which bound electron pairs flow through a material in perfect synchrony, without friction. Conventional superconducting materials reach this state ...
