- Course objectives
- Atomic force microscopy (AFM) is the most employed method from the methods of scanning probe microscopy. During the last ten years AFM has a considerable utilisation in many fields of both the fundamental and applied researches. Its use starts in practice as well. The same statements are true for scannig tunneling microscopy (STM), magnetic force microscopy (MFM), scanning thermic microscopy (STEM), scanning near optics microscopy (SNOM) etc. in a smaller measure. In this lecture theoretical principles of the interaction between the tip of the microscope and the surfaces of samples studied by AFM are described within different approaches of classical physics. This interaction is studied in connection with the two basic modes of AFM, i.e. in connection with a non-contact and contact modes. Further a construction of the atomic force microscope used in practice is decribed. The influence of the force interaction between the tip of the microscope and the surface of the sample on working the whole microscope is presented (in this way a detection by the microscope is described). Basic methods of calibrating the atomic force microscopes are mentioned briefly. A considerable attention is devoted to applying AFM in practice. The applications concerning investigations of surface roughness, upper boundaries of various thin films and structure of these films are discussed mainly. Applications of AFM in biophysics, biology, chemistry and medicine are mentioned too. A possibility of combining AFM with the other methods (e.g. optical methods) are noted as well. Within the lecture the principles of STM, MFM, STEM and SNOM are also explained. Both the theoretical and experimental aspects of these techniques are studied. Applications of STM, MSM, TSM and SNOM are also specified in a brief way. The lecture is completed by many images recorded using the techniques mentioned above at analyzing of various objects taking place in physical research, researches in the other sciences and practice.
