Wave Diffraction and Reciprocal Lattice

Wave Diffraction and Reciprocal Lattice. Most methods for determining the atomic structure of crystals are based of the idea of scattering of radiation. The wavelength of the radiation should be comparable with the distance between atoms ( ).

Energy bands

Energy bands. The free electron model gives us a good insight into many properties of metals, such as the heat capacity , thermal conductivity and electrical conductivity. However , this model fails to help us other important properties. For example,
