Abstract

Four n-i-n GaAs/AlGaAs diodes have been used to demonstrate that at room temperature the carrier blocking is influenced by the X-valley superlattice in a multiquantum barrier. The diode with a Γ-X crossover multiquantum barrier has a current at least three orders lower than the corresponding diode with only a bulk barrier. However, diodes without Γ-X crossover barriers have resistance as low as 10 Ω in spite of whether a multiquantum barrier exists or not. This indicates that the X-valley superlattice plays an important role in blocking the current flowing across/through a multiquantum barrier.
