Abstract(in English) | We clarified the degradation mechanisms for population inversion in THz-QCLs at high temperatures using the non-equilibrium Green's function (NEGF) method and investigated new THz-QCL schemes for further improvement. Using the achievements, we proposed a novel and simple two-well THz-QCL structure that has the scattering injection and diagonal transition schemes. This structure would lead to a realization of wavelength-tunable THz-QCLs, which are not realized in the conventional THz-QCLs. |
