Abstract

Ultrafast excitation of n-doped GaAs layers leads to THz emission from coherent plasma oscillations.¹ The emission frequency of this THz source is given by the simple plasma frequency formula ω_p = (ne²/m^*ϵ)^1/2 wheren is the number of extrinsic electrons which are confined between the surface depletion field and the GaAs substrate.
