Abstract In this paper, ion implantation in collisional and gyro-viscous semiconductor quantum plasmas is shown to excite magneto-acoustic modes under the influence of an ambient magnetic field B 0 . On employing the quantum hydrodynamic (QHD) model coupled with Maxwell’s equations, these modes are systematically analyzed in two characteristic gyro-scale limits. The resulting dispersion relation yields two distinct roots: the upper gyro-scale limit predicts an instability growth rate, while the lower limit corresponds to a damping (decay) rate. A comprehensive numerical investigation of all magneto-acoustic roots is performed, considering both finite collisional effects and gyro-viscous contributions independently. Analytical results are evaluated for typical GaAs plasma parameters, and the corresponding profiles are graphically illustrated. The study reveals that the uniform magnetic-field strength, implanted-ion density, and quantum tunneling potential significantly influence the growth and damping behavior of magneto-acoustic modes.
