A review is presented of work over the last 10 years which has been aimed at trying to
produce a Si‐based THz quantum cascade laser. Potential THz applications and present …

Due to their intuitiveness, flexibility, and relative numerical efficiency, the macroscopic
Maxwell–Bloch (MB) equations are a widely used semiclassical and semi …

n-type Ge/SiGe terahertz quantum cascade lasers are investigated using non-equilibrium
Green's functions calculations. We compare the temperature dependence of the terahertz …

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 …

Silicon-based quantum cascade lasers (QCLs) offer the prospect of integrating coherent
terahertz (THz) radiation sources with silicon microelectronics. Theoretical studies have …

Terahertz (THz) quantum cascade lasers (QCLs) are technologically important laser sources
for the THz range but are complex to model. An efficient extended rate equation model is …

In this paper, we have experimentally and numerically studied the nonradiative
intersubband (ISB) relaxation in n-type Ge/SiGe quantum well (QW) systems. Relaxation …

Quantum cascade lasers (QCLs) are compact sources that have demonstrated high output
powers at terahertz (THz) frequencies. To date, all THz QCLs have been realized in III-V …

The experimental and numerical studies of the transport properties and wave functions of
electrons in GaAs/Al x Ga 1-x As superlattices with weak barriers in a strong electric field …

We present an energy-balance model of the electronic intersubband relaxation in optically
excited n-type Ge/SiGe quantum wells with absorption resonance in the THz range. To this …
