    Electrostatic modes can widely be categorized as acoustic and hybrid waves. We have studied the excitation of electrostatic, comparatively low frequency volume waves, lower-hybrid waves (LHWs) in semiconductor plasma by using a hydrodynamic model. The Hydrodynamic Model consisting upon fluid equations namely momentum balance equation, equation of continuity and the Poisson’s equation have used to study the physical properties and characteristics of semiconductor plasmas consisting upon electron and holes. Radiation pressure is considered as an exciting source in semiconductor plasma systems. For analytical examination of the linear dispersion relation, we elucidated the fluid equations for semiconductor plasmas. In this thesis, for semiconductor plasmas, we have analyzed the LHWs in the presence of radiation pressure, the thermal effects upon plasma species, in addition to the external magnetic field. For numerical analysis, we have used the assistance of Mathematica or MATLAB.
