Substrate orientation and alloy composition effects in n-type SiGe quantum cascade structures

By A. Valavanis, Z. Ikonic, L. Lever, C.A. Evans and R.W. Kelsall


We show using a theoretical self-consistent effective mass/rate equation approach that n-type SiGe-based quantum cascade lasers are potentially made viable by either using the (111) orientation or a Ge-rich substrate
