Abstract(in English) | We have investigated teraherz (THz) radiation from two-dimensional (2D) free carrier Plasma oscillations in selectively doped GaAs/AlGaAs single quantum wells by time-resolved THz emission spectroscopy. By varying the excitation wavelength and power of the pump beam, we are able to discriminate plasmon excitations due to coherent impulsive Raman process and due to incoherent current surge and/or impulsive heating by photoexcited carriers. |
