Abstract
This paper investigates the nonlinear excitation of plasma waves due to the interaction between an electron acoustic pump wave and a hole acoustic sideband wave in cylindrical semiconductor waveguides using nonlinear theory. The coupling between these waves leads to the generation of a beat acoustic wave, forming a three-wave interaction system. Quantum effects like Fermi degenerate pressure, exchange–correlation, and Bohm potentials, which play a critical role in modulating the wave dynamics, are incorporated. Using the Quantum Hydrodynamic Model, we derive and analyze the dispersion relations of these waves and the growth rates of beat waves under phase-matching conditions. Numerical results show that the nonlinearity emerges through ponderomotive forces, leading to significant amplification of the beat wave. The growth rate evolution is examined under the influence of temperature, electron density, and wave vector that reveals the enhanced wave coupling and energy transfer by lower temperatures, higher electron densities due to quantum effects, as well as shorter wavelengths and higher potential pump acoustic waves as optimizing conditions. These findings have potential applications in semiconductor device design, where controlled nonlinear wave interactions are essential for optimizing performance.
