Groening, Journal of Materials Chemistry, 14, 933, 2004;Fig 4.39;Consider two copper wires separated only by their surface oxide layer (CuO). Classically, since the oxide layer is an insulator, no current should be possible through the two copper wires. Suppose that for the free electrons in copper, the surface layer looks like a square potential energy barrier of height of 10eV. Consider an oxide layer thickness of 5nm and evaluate the transmission coefficient for conduction electron with kinetic energy of 7eV. What will be the transmission coefficient if the oxide barrier is 1nm?;Fig 3.19;Potential Box: Three Quantum Numbers;Fig 3.20;Electron wavefunctions and the electron energy are obtained by solving the Schr?dinger equation ;Fig 3.21;;Fig 3.22;Electron energy is quantized;Fig 3.23;Fig 3.24;Fig 3.25;Electron probability distribution in the hydrogen atom;Fig 3.26;Ionization energy from the n-level for an outer electron;Fig 3.27;Orbital Angular Momentum and S
