Townsend, P, Paul, DJ, Lynch, SA, Kelsall, RW, Ikonic, Z, Harrison, P, Norris, DJ, Cullis, AG, Zhang, J, Li, X, Pidgeon, CR, Murdin, BN and Murzyn, P (2005) LO phonon scattering as a depopulation mechanism in Si/SiGe quantum cascades In: 2nd IEEE International Conference on Group IV Photonics, 2005-09-21 - 2005-09-23, Antwerp, BELGIUM.
The linear optical phonon as a fast depopulation mechanism in Si/SiGe quantum cascade devices. Confirmed by pump-probe, the lifetime measurement is limited by the optical cycle of the source (<2 ps). Fourier transform spectroscopy shows intersubband electroluminescence with good agreement to theory.
