Action spectra of gaas/algaas multiple quantum wells exhibiting terahertz emission peak at excitation energies below the bandgap
We present terahertz (THz) emission of optically pumped 5- and I2.5-nm GaAs/AIGaAs multiple quantum wells (MQWs) even at excitation energies below the bandgap. The effect ofthe externally applied magnetic field parallel to the MQW plain is to enhance or reduce the THz emission intensity for the up o...
