Conductance oscillations of antiferromagnetic layer tunnel junctions

چکیده
We study conductance oscillations of antiferromagnetic layer tunnel junctions composed topological insulators such as ${\mathrm{MnBi}}_{2}{\mathrm{Te}}_{4}$. In the presence an in-plane magnetic field, we find that two terminal differential conductances across junction oscillates a function field strength. Notably, quantum interference at weak fields for even-layer case is distinctive from odd-layer due to scattering phase shift $\ensuremath{\pi}$. Consequently, vanishes (maximized) integer flux quanta (odd-layer) junctions. The manifest layer-dependent in which symmetries and phases play essential roles. numerical calculations, observe undergoes evolution superconducting device-like Fraunhofer-like length increases.

Strong conductance variation in conformationally constrained oligosilane tunnel junctions.
The effects of molecular conformation on conductance in oligosilane-bridged metal-molecule-metal junctions are studied theoretically using density functional theory combined with a nonequilibrium Green's function approach. Varying the internal SiSiSiSi dihedral angles in hexasilane diamine chains changes the conductance by up to 3 orders of magnitude. This conformational dependence is due to th...
متن کاملSidewall GaAs tunnel junctions fabricated using molecular layer epitaxy.
In this article we review the fundamental properties and applications of sidewall GaAs tunnel junctions. Heavily impurity-doped GaAs epitaxial layers were prepared using molecular layer epitaxy (MLE), in which intermittent injections of precursors in ultrahigh vacuum were applied, and sidewall tunnel junctions were fabricated using a combination of device mesa wet etching of the GaAs MLE layer ...
