Influence of Collisions on the Resonances in Bounded Semiconductor Plasmas

The influence of the collisions on the resonances in a bounded non‐isothermal semiconductor plasma in a magnetic field is considered on the basis of the two‐component magnetohydrodynamics. The semiconductor plasma is placed between two metal electrodes. The external magnetic field is perpendicular to the exciting ac electric field. The frequencies of the excited resonances of “hole sound”‐type are found. The results can also be used in the absence of a magnetic field. They can also be applied for a bounded gaseous plasma. When the collision frequencies are neglected, and without magnetic field, the formulae derived coincide with the well‐known resonance formulae, published previously. [Russian Text Ignored].
