The elementary charge, usually denoted as e, is the electric charge carried by a single proton, or equivalently, the negation (opposite) of the electric charge carried by a single electron. This elementary charge is a fundamental physical constant. To avoid confusion over its sign, e is sometimes called the elementary positive charge. This charge has a measured value of approximately 1.602176565(35)Ã10â19 coulombs. In the cgs system, e is 4.80320425(10)Ã10â10 statcoulombs.
Spintronics, or spin transport electronics, is a sort of emerging technology that scientists have been studying for a while in an attempt to leverage the encoding posibilities in an electron’s spin, in addition to its electrical charge. Recently, researchers at IBM Zurich have made a huge leap forward in turning spintronics into a viable technology [...]
