Scanning tunnelling microscopes (STMs) have been used for nearly three decades to study the surfaces of metals and semiconductors. But now physicists in Germany have discovered that the instruments ...

The electron is responsible for charge and spin transport in conventional metals. In contrast, the existence of well-defined electronic excitations in the metallic state of high-temperature ...

Discover the Fermi Paradox — why, in a vast universe full of stars and planets, haven't we found extraterrestrial life? Explore the theories behind this great mystery. The universe is vast, ancient, ...

Scanning tunneling microscopy (STM) is an experimental technique based on the principles of quantum tunneling of electrons between two electrodes separated by a potential barrier, typically used for ...

Federal regulators have approved construction of the Fermi 3 nuclear reactor near Monroe, although it may not ever get built. The Nuclear Regulatory Commission announced Thursday afternoon that after ...
