摘要：

The heterostructure conduction band offset, Delta E-c, in InAs/GaAs self-organized quantum dots has been measured by deep level transient spectroscopy. Measurements were made with Au-Al0.18Ga0.82As Schottky diodes in which the multilayer dots are embedded in the ternary layer. The estimated value of the band offset Delta E-c = 341 +/- 30 meV.
