The most extensive use of semiconductors, such as silicon or germanium, including their use as transistors, arises from their behavior when, after being sufficiently purified of atoms other than the basic element (e.g., silicon or germanium), very small amounts of special impurities are carefully introduced. While the methods for first purifying then adding small amounts […]

Farthest galaxy ever seen spotted by Hubble The Hubble Space Telescope has spotted the farthest galaxy found so far, 13.4 billion light-years away, according to findings published in the Astrophysical Journal. Astronomers say the galaxy, GN-z11, dates back to just 400 million years after the Big Bang. The Christian Science Monitor Mars’ outer layers shifted […]

A visionary perspective of molecular electronics is the use of single molecules as functional entities in electronic devices. In this context, some of the most important components are molecular switches, which are molecules that can be interconverted reversibly between at least two stable states, one for the OFF and one for the ON. In order […]

The most prevalent use today of semiconductors is forming them into transistors, the basic electronic building blocks of all “solid-state electronics” and computer microchips. Semiconductors are the most important materials in the burgeoning revolution in computers and other electronic devices today. Such applications also arose, beginning in the 1930s, from the quantum mechanics of the […]
