Shockley states are thus states that arise due to the change in the electron potential associated solely with the crystal termination. This approach is suited to describe normal metals and some narrow gap semiconductors. Figure 3 shows an example of a Shockley state, derived using the nearly free electron … See more Surface states are electronic states found at the surface of materials. They are formed due to the sharp transition from solid material that ends with a surface and are found only at the atom layers closest to the surface. The … See more Surface states in metals A simple model for the derivation of the basic properties of states at a metal surface is a semi-infinite periodic chain of identical atoms. In … See more Surface states originating from clean and well ordered surfaces are usually called intrinsic. These states include states originating from reconstructed surfaces, where the two-dimensional translational symmetry gives rise to the band structure in the k space of the … See more A naturally simple but fundamental question is how many surface states are in a band gap in a one-dimensional crystal of length See more As stated by Bloch's theorem, eigenstates of the single-electron Schrödinger equation with a perfectly periodic potential, a crystal, are See more Surface states that are calculated in the framework of a tight-binding model are often called Tamm states.
