in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...

A theory of electron injection into diffusive shock acceleration (DSA) for the generation cosmic-ray electrons at collisionless shocks is presented. We consider a recently proposed particle mechanism called stochastic drift (SSDA). find that SSDA may be understood as an oblique finite thickness. More specifically, it described by solution to diffusion-convection equation particles with characte...
