Abstract
A detailed analysis of hole transport in cascaded quantum well structures is performed using ensemble Monte Carlo simulations. The hole subband structure is calculated using the model, and then used to find carrier relaxation rates due to the alloy disorder, acoustic and optical phonon scattering. The simulation accounts for the in-plane -space anisotropy of both the hole subband structure and the scattering rates. Results are presented for prototype terahertz quantum cascade structures.
