Consider a piece of conductor which is under a DC bias. Solving time-independent Schrodinger equation we have electron wave function which is time-independent and shows special probability for being in each position of the system. How can one say about transmission of electron from one point to another while the electron is always in all the space with the constant (time-independent) probability.(adsbygoogle = window.adsbygoogle || []).push({});
