Under external influences, the electronic topological transition (ETT) may be realized in metals: the topological properties of the metal Fermi-surface are changed, that is, either its separate voids are generated or disappear, or the closed Fermi surface is transformed into an open one. The peculiarity of the density of states, appearing at the ETT, involves a number of peculiarities of the thermodynamical and kinetic properties of the metal. In the present review we shall describe the significant successes achieved in the past decade in the experimental and theoretical investigations of the kinetic properties of metals undergoing the ETT. The exposed microscopic ETT theory takes into account the temperature diffuseness of the Fermi surface, as well as possible processes of electron scattering. The peculiarities of the metal thermopower and conductivity in the ETT vicinity are discussed in detail and an analysis of the abundant experimental data is carried out. The influence of the ETT upon the absorption of longitudinal sound propagating in the metal undergoing this ETT is investigated. The change in the electro-physical properties of various tunnel structures, the electrodes of which are subject to the ETT, is discussed. |
