Transmission Coefficient-electron energy characteristics in AlGaAs-GaAs compositival superlattices are calculated. Injecting electrons from AlGaAs cathode to GaAs layer, electrons are reflected slightly at the AlGaAs-GaAs interface. Increasing superlattice cycle, largequantum interference effect appears due to quantum mechanical reflection at respective interface. New negative resistance in AlGaAs-GaAs superlattices owing to quantum interference effects is proposed and analysed. Physics behind negative resistance are discussed.
