Abstract :
We demonstrate a novel carrier transport mechanism in semiconductor superlattices. Experimental results show that the higher-subband states positioned above the Γ ground state in a quantum well (QW), i.e., X in the barrier and L in the QW subband states, greatly influence the electron transport in some superlattices under an electric field
