Annotation
This lecture deals with specific properties of solid surfaces and with preparation methods of surfaces for modern technologies as well as with preparation of continuous and non-continuous layers having dimensions in nanometer scale. In frame of this lecture we will discuss basic experimental techniques for investigation and characterization of clean surfaces, ultra-thin layers and nanometer structures (electronic structure, crystallographic structure, morphology, chemical state).
