- Abstract
- The method of nonequilibrium Greens functions allows
for a spatial and energetical resolution of the electron
current in Quantum Cascade Lasers. While scattering
does not change the spatial position of carriers, the entire spatial evolution of charge can be attributed to coherent transport by complex wave functions. We discuss the hierarchy of transport models and derive the density matrix equations as well as the hopping model starting from the nonequilibrium Greens functions approach.
