An extended density matrix model applied to silicon-based terahertz quantum cascade lasers
T. V. Dinh, A. Valavanis, L. J. M. Lever +2
Silicon-based terahertz quantum cascade lasers (QCLs) offer potential advantages over existing III-V devices. Although coherent electron transport effects are known to be important…

Theory and design of quantum cascade lasers in (111) n-type Si/SiGe
A. Valavanis, L. Lever, C. A. Evans +2
Although most work toward the realization of group IV quantum cascade lasers (QCLs) has focused on valence-band transitions, there are many desirable properties associated with the…

Intervalley splitting and intersubband transitions in n-type Si/SiGe quantum wells: pseudopotential vs. effective mass calculation
A. Valavanis, Z. Ikonić, R. W. Kelsall
Intervalley mixing between conduction-band states in low-dimensional Si/SiGe heterostructures induces splitting between nominally degenerate energy levels. The symmetric double-val…
