New approach to resonant transmission in nanostructures — •Oleg Kidun1, Jamal Berakdar1, and Natasha Fominykh2 — 1MPI für Mikrostrukturphysik, Halle, Germany — 2Institute of Physics, St. Petersburg State University, St. Petersburg, Russia
We explore the resonant transmission probability in artificially fabricated nanosystems such as semiconductor quantum wells or quantum dots. We introduce the concept of spatially varying conductance and provide determining equations for this quantity. The theory resembles the well-known variable phase method [1-2], applied for 3D systems. Application of the suggested approach for particular nanostructures and a comparison of the theoretical results with experimental measurements are presented and discussed.
