Far infrared surface electromagnetic waves propagation on A3B5 semiconductors
Abstract
The real and imaginary parts of surface electromagnetic waves (SEW) refraction index nef in n-type InSb, GaAs and InP have been measured in FIR region (ν=85-142 cm-1). The nef measurements allowed to determine plasma frequency νp and plasmon damping γ. The obtained nonlinear SEW propagation distance L dependence on Te impurity concentration in GaAs (N=1017-1019 cm-3) was explained taking into account the conduction band nonparabolity as well as the presence of isostructural phase transition at N=2×1010 cm-3.
