EFFECT OF QUANTUM PARAMETER?H ON LONGITUDINAL ELECTRO? KINETIC WAVE CHARACTERISTICS IN MAGNETISED SEMICONDUCTOR PLASMA

Using quantum hydrodynamic model, linear characteristics of longitudinal electro-kinetic wave have been studied both analytically and numerically, in one component magnetised dense semiconductor quantum plasma in which quantum effects are incorporated through non-dimensional quantum parameter-H. It is shown that presence of magnetic field modifies the linear dispersion characteristics of longitudinal electro-kinetic wave and the quantum parameter-H makes the excitation of two novel modes possible whereas the combine presence of quantum parameter-H and magnetostatic field induce four novel modes of propagation. The structure of the modes of longitudinal electro-kinetic wave is shown to be significantly affected by the quantum parameter-H and applied magnetostatic field.
