Dataset description
We demonstrate an extraction-controlled terahertz frequency quantum cascade laser experimentally, and modelled it with an extended density matrix approach. In our design, a diagonal LO-phonon scattering process is used to achieve both carrier extraction and injection simultaneously. Its simplicity makes it an ideal platform to investigate the scattering injection process for high temperature operation of THz QCLs. Figure 1 shows the band structure and electronic wave functions, and table 1 details the structural parameters of four designs. Figure 2 and figure 3 are the characterisation results, including LIV curves and emission spectra at different temperature. Figures 4-8 are the numerical results, including the calculated IV curves, the carrier transport paths, the temperature evolution of carrier transport, and the effects of radiative diagonality on the current and the optical gain.
