Abstract
The complex electronic band structure of a one-dimensional solid is de scribed using a one-dimensional scattering approach. The method yields the value of the wave function and its derivative between the atomic layers. These values can be matched at the surface to the correspondin g values of the wave function on the vacuum side. The method is compar ed to the two-band approximation of the nearly free electron model. Ad vantages of the proposed scheme are the easy adaption for layered syst ems and alloys.
