Abstract: Metal-semiconductor interfaces have a long history $[1,2]$ and are crucially important to modern micro- and nanoelectronic devices, and together with the spatial diminishing of their active areas are the details of interface electronic structure becoming of the paramount importance for the control of the charge carrier transport through the interface. Modern experimental techniques $[3]$ already allow us to investigate the properties of the interface region with atomic resolution, but the unifying theoretical model does still not exist which is especially true for the non-ideal interfaces where the presence of foreign atoms or intentionally inserted layer or various defects are causing deviations from the ideal cases $[4]$. First we will review the basic concepts and theories of the metal-semiconductor interface, and then we will focus on the origin and the influence of disorder. References: $[1]$ R. T. Tung, Mat. Sci.
