INVESTIGATION OF THE NON-EQUILIBRIUM IMPACT ON THE PROPERTIES OF A SUPERCONDUCTOR USING A PLASMA SUPERCONDUCTIVITY MECHANISM

The results of theoretical studies of a semiconductor structure are presented which, upon irradiation with a particle stream or light, transforms into a superconducting phase state. The work is carried out: – analysis of ion-acoustic oscillations in non-degenerate and degenerate plasma; – analysis of the possibility of using the jelly model to describe the weak coupling and strong coupling; – determination of the value of the order parameter when the equilibrium distribution is replaced by a non-equilibrium distribution function; – analysis of the dispersion properties of the medium for a non-equilibrium stationary distribution of charged particle; – determination of the critical temperature of a superconducting transition when using the plasma mechanism for describing superconductivity. The aim of research: determination of the frequency of oscillations of the "ion sound" type with sufficiently large mobility of the sites of the absence of electrons (holes); determination of the method for calculating the damping of ion-acoustic oscillations, which are determined by the imaginary part of the dielectric constant (decrement damping); numerically solution of the equation for the width of the energy gap; determination of the method of estimating the critical temperature of a superconductor in the plasma description of the process of the onset of superconductivity
