Energy Band Design for a Terahertz Si/SiGe Quantum Cascade Laser
太赫兹Si/SiGe量子级联激光器的能带设计

The eigenenergies of confined states in Si/SiGe/Si quantum wells are calculated with nextnano3 software for the design of terahertz Si/SiGe QCLs.The results indicate that the structure of the Si/SiGe quantum cascade may be optimized by using a strain-symmetric heterostructure consisting of a Si_ 1-xGe_x(0.27
