【 摘 要 】

In communication processes, amplitude modulation is very helpful to save power using a single band transmission. Using the hydrodynamical description of semiconductor plasma analytical investigations are made for the amplitude modulation as well as demodulation of an electromagnetic wave in magnetized ion implanted semiconductor plasmas having strain dependent dielectric constants. Analysis is made under different wave number regimes over a wide range of cyclotron frequencies without and with colloids. Numerical estimations are made for n-doped BaTiO3crystal irradiated by pump wave frequency 1.78 × 1013s-1. It has been found that ion implantation of negatively charged colloids modifies nearly ≈ 105of magnitude of amplitude modulation and demodulation processes. Ion implantation plays a key role in development of optoelectronics.
