Practical implementation of m-Plane GaN resonant-phonon Terahertz quantum cascade laser
Within this study, we have theoretically analyzed a three quantum well period m-plane GaN/Al0.14Ga0.86N THz-QCL structure based on a resonant-phonon (RP) scattering scheme. Our main goal was to design a practical structure and to avoid the…
