ABSTRACT
Evidence of the elastic and inelastic components of sequential resonant tunneling in AlAs/GaAs superlattices is presented. Magnetic field data (B parallel to current flow) show that as the energy spacing between the Landau levels in the quantum wells is changed, the corresponding density of states available for tunneling via inelastic scattering paths is changed and thus the magnetic field influences the inelastic portion of the current.
