Coherent Control of Perfect Optical Vortex Through Four-Wave Mixing in an Asymmetric Semiconductor Double Quantum Well

open access: yesFrontiers in Physics, 2022
A scheme for the coherent control of perfect optical vortex (POV) in an asymmetric semiconductor double quantum well (SDQW) nanostructure is proposed by exploiting the tunneling-induced highly efficient four-wave mixing (FWM).

Impact of Resonant Tunneling on Optical Properties of InAs/InP Quantum Dot Lasers

open access: yesApplied Sciences
Electronic coupling within InAs/InP quantum dots (QDs) influences carrier lifetime and thus QD laser performance. In this work, vertical electronic coupling between QDs is theoretically investigated based on a structure of five-layer QD stacks.

Anomalous zero-temperature magnetopolaronic blockade of resonant electron tunneling in Majorana-resonant-level single-electron transistor

open access: yesCondensed Matter Physics, 2018
The magnetopolaronic generalization of a Majorana-resonant-level (MRL) model is considered for a single-level vibrating quantum dot coupled to two half-infinite g=1/2 Tomonaga-Luttinger liquid (TLL) leads.

All-Graphene Planar Double-Quantum-Dot Resonant Tunneling Diodes

open access: yesIEEE Journal of the Electron Devices Society, 2016
This paper proposes a new class of resonant tunneling diodes (RTDs) that are planar and realizable with a single graphene nanoribbon. Unlike conventional RTDs, which incorporate vertical quantum well regions, the proposed devices incorporate two confined

Inelastic scattering in resonant tunneling [PDF]

open access: yesPhysical Review B, 1989
The exact resonant-tunneling transmission probability for an electron interacting with phonons is presented in the limit that the elastic coupling to the leads is independent of energy. The phonons produce transmission sidebands but do not affect the integrated transmission probability or the escape rate of the electron from the resonant site.
