Web1 Nov 2024 · In relation to the Kronig–Penney model, there has been much study undertaken into the finite system that possesses open boundary conditions. In such cases, charge quanta may be pumped through the chain by a suitable adiabatic deformation of parameters and the quantisation is of a topological origin [ 18, 19 ]. WebThe Kronig-Penney one-dimensional model Purpose: to demonstrate that in solids, where many atoms stay closely, the interference between atoms will create allowed and …
