Determinations of electrokinetic properties of semiconducting materials for making nanocathods

Condensed matter physics

The interaction of the pulse laser radiation with the solid state samples were studied using the method of the femtosecond laser reflection spectroscopy. The time dependences of the induced reflection coefficient were analyzed. This analysis allowed to measure the relaxation time of free carriers and to formulate the basic technique of development of nanocomposite cathodes based on rare-earth metals with semiconductor impurities.
