Room temperature negative differential resistance in terahertz quantum cascade laser structures
The mechanisms that limit the temperature performance of GaAs/Al[subscript 0.15]GaAs-based terahertz quantum cascade lasers (THz-QCLs) have been identified as thermally activated LO-phonon scattering and leakage of charge carriers into the continuum. Consequently, the combination of highly diagonal...
