Sequential resonant tunneling in quantum cascade lasers
arXiv:0810.0146 · doi:10.1103/PhysRevB.78.155328
Abstract
A model of sequential resonant tunneling transport between two-dimensional subbands that takes into account explicitly elastic scattering is investigated. It is compared to transport measurements performed on quantum cascade lasers where resonant tunneling processes are known to be dominating. Excellent agreement is found between experiment and theory over a large range of current, temperature and device structures.
