Title

PARAMETRIC INTERACTION OF ACOUSTIC PHONONS IN MAGNETIZED SEMICONDUCTOR PLASMAS

Abstract

Using the hydrodynamic model of semiconductor plasmas, a detailed analytical investigation is made to study parametric amplification in magnetized piezoelectric as well as non-piezoelectric semiconductors. The origin of nonlinear interaction is taken to be in the second-order optical susceptibility (2) arising from nonlinear induced current density. The threshold value of pump intensity I0,th is obtained for crystals. Parametric gain constants are obtained for different situations of practical interest, i.e. (i) for piezoelectric coupling only gp, (ii) for deformation potential coupling only gd, (iii) for both the couplings gb. Numerical estimates are made for n-InSb crystal duly irradiated by 10.6 m CO2 laser. It is found that the application of large d.c. magnetic field significantly reduces the threshold pump intensity I0,th for the onset of parametric amplification. At sufficiently high magnetic field (i.e. c ~ 0), I0,th is reduced by approx. 3.56 times. The parametric gain constants (gp, gd and gb) are found to increase with increasing pump intensity I0 (> I0,th), wave number k, magnetic field Bs (c), and scattering angle . Moreover, it is found that gb > gp > gd.
