    Understanding Orbital Decay: Kinetic Energy & Mechanical Energy

    Hey guys. Could someone please explain orbital decay to me, with reference to the kinetic energy lost, and stuff like that. Also i would like to know how the equation for mechanical energy in orbits is derived, and how it is used. Thanks!

    Electron hole theory in Semiconductors

    Hm...I sort of understand the whole idea of the electron leaving to the conductor band leaving behind a hole which can act as a positive charge electron. But I don't understand how the electrons and hole will move when that piece of semiconducting material is used in a circuit. (Its really...

    Electron hole theory in Semiconductors

    Hi guys. Could someone please explain to me this electron hole theory that people use to describe the behavior of electrons inside semiconductors? How do these holes move, in and out of a potential difference? Thanks guys.
