Material configurations for n-type silicon-based terahertz quantum cascade lasers
A. Valavanis, T. V. Dinh, L. J. M. Lever +2
Silicon-based quantum cascade lasers (QCLs) offer the prospect of integrating coherent THz radiation sources with silicon microelectronics. Theoretical studies have proposed a vari…

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…
