We present a detailed study of the polarization dependence of subband absorption and photoconductivity in Si/SiGe quantum wells. For samples with a hole concentration of p :2.8;10 cm\, both p-and s-polarized absorptions have been observed and transitions to several excited states are clearly identif

A detailed study of the polarization dependence of subband absorption and photoconductivity in pseudomorphic p-type Si/Si 0.64 Ge 0.36 quantum wells is presented. The fabricated quantum well infrared photodetectors (QWIP) show a photoresponse between 3 and 8 µm with a peak-wavelength of λ p = 5 µm u

A theory is presented for electromagnetic energy transfer and absorption mediated by quasi-twodimensional excitons in regular multiple-quantum-well (MQW) structures. The absorptivity, absorption coefficient and their integrals over the photon frequency are generally expressed as functions of the rat
