Many-body Tunneling and Nonequilibrium Dynamics of Doublons in Strongly Correlated Quantum Dots

Scientific Reports, 2017
Quantum tunneling dominates coherent transport at low temperatures in many systems of great interest. In this work we report a many–body tunneling (MBT), by nonperturbatively solving the Anderson multi-impurity model, and identify it a fundamental ...

Nanoscale nonlocal thermal transport and thermal field emission in high-current resonant tunnel structures

Scientific Reports
We present a nonlinear model of thermal field emission in resonant tunneling nanostructures with multiple barriers and potential wells, based on an accurate determination of the quantum potential shape and a rigorous solution of the Schrödinger equation,

Quasi‐Resonant Tunneling Transport in Magnetic CrBr3

Advanced Physics Research
Tunneling techniques are pivotal for probing 2D magnetic materials. While the Fowler‐Nordheim model describes tunneling in bulk materials through bias‐induced triangular potentials, van der Waals layered systems require special consideration of ...

Emergence of Negative Differential Resistance Through Hole Resonant Tunneling in GeSn/GeSiSn Double Barrier Structure

IEEE Journal of the Electron Devices Society
We examined the fabrication and the operation of GeSn/GeSiSn resonant tunneling diode (RTD) and demonstrated the observation of negative differential resistance (NDR) at a low temperature through the hole resonant tunneling.

Tunneling of two-dimensional surface polaritons through plasmonic nanoplates on atomically thin crystals

Nanophotonics
We theoretically investigate the tunneling of two-dimensional surface polaritons (2DSPs) through plasmonic nanoplates on atomically thin crystals. By developing an analytic model based on coupled-mode theory, we examine the tunneling efficiency as a ...
