The FOs phenomenon has some interesting applications beyond catalysis. Among others FOs may be used to calculate Fermi surfaces and dispersion relations as well as dispersion of the surface states and even allow to detect and characterize depth of defects below the surface using STM. FOs may also be explored in the fabrication of diluted magnetic semiconductors and spin-glasses. All systems with non-free electron gases should exhibit phenomena such as Friedel Oscillations (FOs). Therefore, addressing these situations should become a standard procedure in both chemical and physical contexts. Our aim is to enhance the under-Fig. Simulated temperature dependence of Friedel oscillations on Au(111). The curve obtained for 4K coincides with oscillations predicted by LDOS(E, x) = (1 -J 0 (2k F x)C 0 , where J 0 -is a standardized zero-order Bessel function of the first kind, and C 0 is constant. The fitting parameters have been taken from earlier photoemission data .

Additionally, surface physics should devote more effort to providing strict analytical explanations of the chemical aspects and actively disseminate this knowledge.
