The electronic transport properties in a sawtooth-doping superlattice (SDS) with different delta-doping densities have been studied. Multiple-state negative differential resistance (NDR) performance is exhibited due to the strong field effect and the avalanche multiplication mechanism. The different delta-doping densities contribute to the different barrier heights in the superlattice periods which cause various influences on the whole transport properties. Therefore, the different NDR phenomena in the current-voltage characteristics are clearly observed.
