Electronic Conductivity in Open Cylindrical Two-Barrier Symmetric Resonance Tunnel Structure

Active conductivity of plane two-barrier resonance tunnel structure as operating element of quantum cascade laser or detector

Within the model of rectangular potentials and different effective masses of electrons in different elements of plane two-barrier resonance tunnel structure there is developed a theory of spectral parameters of quasi-stationary states and active conductivity for the case of mono-energetic electronic current interacting with electromagnetic field. It is shown that the two-barrier resonance tunne...

Interaction between two cylindrical inclusions in a symmetric lipid bilayer

We calculate the membrane-mediated interaction between two cylindrical inclusions in a symmetric lipid bilayer. Our theory takes two contributions to the free energy into account, the elastic behavior of the membrane and the conformational restrictions that the flexible hydrocarbon chains of the lipids experience in the vicinity of a rigid inclusion. The description of the elastic behavior is b...

Electronic structure of FeÕsemiconductorÕFe„001... tunnel junctions

The electronic ground-state properties of Fe/semiconductor/Fe~001! tunnel junctions are studied by means of the ab initio screened Korringa-Kohn-Rostoker method. We focus on the magnetic properties, charge transfer, local, and qi-resolved density of states of these systems. We consider in detail Fe/ZnSe/Fe~001! tunnel junctions and compare their electronic properties with junctions with Si and ...

Dynamic conductivity of symmetric three-barrier plane nanosystem in constant electric field

The theory of dynamic conductivity of nanosystem is developed within the model of rectangular potentials and different effective masses of electron in open three-barrier resonance-tunnel structure in a constant homogeneous electric field. The application of this theory for the improvement of operating characteristics of quantum cascade laser active region (for the experimentally investigated In...
