Resonant tunneling in GaAs/AlGaAs superlattices with periodic potential profiles
The effect of the periodicity over the transmission property in semiconductor superlattices is theoretically investigated. It is found that the increasing the number of periods in GaAs/AlGaAs multiple quantum wells (MQW) introduces additional resonant states. it is also noted that the asymmetry of periodic potential profile is one key parameter in reaching high values of the transmission coefficient. These results can provide a new method to obtain filters in the submillimeter range.
