Numerical Study of Electronic States in a Quantum Wire at Crossing Heterointerfaces
We demonstrate that the confinement produced by the internal electric fields at crossing heterointerfaces is sufficient to produce a bound electronic state in two dimensions. The potential profiles and electronic states are obtained by numerically solving the Poisson and Schrödinger equations using the Finite Element Method. We also investigate the feasibility of parallelizing the calculations on the local element level by using a cluster of networked workstations as a distributed computational resource.
