Why is it important?
Existing methods of quantum mechanical characterizations of semiconductor heterostructures do not correctly describe how the electron crosses the interface. We have created an algorithm that accounts for this deficiency and reveals that electrons prefer to localize on one side of an interface depending on the effective mass of the charge carrier.
Perspectives
While computer aided design has often been applied to mechanical devices, increasingly theory is assisting the synthesis of new molecules and materials. The new methods presented in our article will help researchers design new materials with targeted properties more accurately.
