Essays on Physics Chemistry

Physics chemistry ATHENS, Ohio -- Todays computers and other technological gizmos operate on electronic charges, but researchers predict that a new contemporaries of smaller, faster, more efficient devices could be developed based on another scientific concept -- electronic birle. The problem, however, is that researchers have show it challenging to control or predict spin which keeps practical(a) applications out of reach.

But physicists in Europe, California and at Ohio University without delay have found a way to manipulate the spin of an electron with a jolt of potentiality from a battery, accord to research findings published in the recent issue of the diary Physical Review Letters. In the new study, scientists applied voltage to the electron in a quantum dot, which is a tiny, nanometer-sized semiconductor. The burst of violence changed the direction of the electrons spin -- which can move either up or down. This also caused it to emit a small particle of light called a photon, explai...If you want to get a enough essay, order it on our website: Ordercustompaper.com
