Geometry engineering of tunneling transistors in transition metal dichalcogenide nanoribbon heterojunctions

Communications Physics
Graphene nanoribbon heterojunctions are promising one-dimensional materials for quantum electronics due to their tunable bandgap and sizable quantum confinement.

Transport Properties of One-Dimensional van der Waals Heterostructures Based on Molybdenum Dichalcogenides

Crystals
The transport properties of one-dimensional van der Waals nanodevices composed of carbon nanotubes (CNTs), hexagonal boron nitride (hBN) nanotubes, and molybdenum dichalcogenide (MoX2) nanotubes were investigated within the framework of density ...

Resonant Tunneling Properties of Gaussian Double Barrier Potential and Effect of the Electric Field Bias

Cumhuriyet Science Journal, 2019
Resonant tunneling properties of finite Gaussian double quantum barrierstructure are studied in the absence and presence of electric field bias. Non-equilibriumGreen's function method based on the finite difference method is used.

Resonant Tunnel Magnetoresistance in a Double Magnetic Tunnel Junction

Journal of Superconductivity and Novel Magnetism, 2011
We present quasi-classical approach to calculate a spin-dependent current and tunnel magnetoresistance (TMR) in double magnetic tunnel junctions (DMTJ) FML/I/FMW/I/FMR, where the magnetization of the middle ferromagnetic metal layer FMW can be aligned parallel or antiparallel with respect to the fixed magnetizations of the left FML and right FMR ...

RESONANT TUNNELING AND RESONANT EXCITATION TRANSFER [PDF]

Condensed Matter Nuclear Science, 2005
Issues involved in the tunneling of deuterons in metal deuterides are considered in relation to experimental claims of anomalies in metal deuterides. From earlier studies, screening is thought to be similar to the case of molecular D2. Resonant tunneling has been advocated in the literature as a possible mechanism to achieve tunneling enhancements.
