We have investigated the tunneling 1-V characteristics of Alo.3Gao.TAs/GaAs MQW diodes with different electron densities, Ns. Clear periodic negative differential resistances (NDRs) are observed for the samples with low N,, while NDRs are completely absent in thefirst plateau region of the I V chara
