In this lecture we shall present numerous kinetic phenomena whose explanation requires application of Boltzmann equation or Monte Carlo (MC) simulations. These phenomena are usually manifested in counter-intuitive behaviour of transport and rate coefficients of electron and ion swarms that cannot be predicted simply from the energy dependence of the relevant cross sections. There are several classes of the observed/predicted kinetic phenomena:
1. in equilibrium with the external electric field: Negative Differential Conductivity, Anisotropic Diffusion, Saturated conductivity due to inelastic collisions;
2. In temporal relaxation: transient negative mobility, diffusion heating or cooling or attachment induced heating or cooling of electron or positron swarms due to non-conservative nature of the collisional processes;
3. Relaxation in crossed time varying electric and magnetic fields; negative transient diffusion, anomalous diffusion;
4. Kinetic phenomena in the vicinity of conductive or dielectric surfaces: selective acceleration of ions and neutrals towards the surfaces due to double layers or electrode sheaths;
5. Kinetic phenomena on surfaces: selective charging and removal of charges from the surfaces and structures: …
In addition to the explanation of the physics of these phenomena we shall describe how to control them having in mind potential applications in nano-electronics and technologies for the treatment of modern materials and biological samples.
