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…

Intersubband carrier scattering in n- and p-Si/SiGe quantum wells with diffuse interfaces
A. Valavanis, Z. Ikonić, R. W. Kelsall
Scattering rate calculations in two-dimensional Si/SiGe systems have typically been restricted to rectangular Ge profiles at interfaces between layers. Real interfaces, however, ma…

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…
