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.
