摘要：

The properties of materials not only rely on interactions inside the Schrodinger equation, but also on the boundary conditions at the interfaces and the boundaries of different materials, also on the continuity of electron density and chemical potential. Electron tunnelling is responsible for the creation of a 'quantum bag' at free ends. The continuity of electron density responsible for the internal stresses at surfaces in contact and the continuity of chemical potential causes transference of electrons from one side to the other resulting to the formation of a double layer of charges at the interface.
