Chirped solitons in discrete electrical transmission line

Results in Physics, 2020
I¸n this paper, we investigate the solitary waves to the discrete nonlinear electrical transmission lines with resonant tunneling diode (RTD). We derive the envelope Ginzburg Landau (GL) equation to the lattice by employing reductive perturbation method ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Origin of Dark Current Robustness in Photomultiplication Organic Photodetectors Enabled by Ionic Conjugated Electron‐Blocking Layers

Advanced Materials, EarlyView.
Ionic conjugated polyelectrolyte electron‐blocking layers enable photomultiplication organic photodetectors with dark current robustness up to −10 V and external quantum efficiencies exceeding 3000%. Fowler–Nordheim tunneling, interfacial dipole, trap density of states, and noise analyses reveal how ionic conjugated polyelectrolytes suppress electron ...

Atomic-scale Authentication with Resonant Tunneling Diodes [PDF]

MRS Advances, 2016
The room temperature electronic characteristics of resonant tunneling diodes (RTDs) containing AlAs/InGaAs quantum wells are studied. Differences in the peak current and voltages, associated with device-to-device variations in the structure and width of the quantum well are analyzed.

A Universal van der Waals Tunneling Injector for Monolayer CMOS

Advanced Materials, EarlyView.
A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Resonant tunneling diode oscillators for optical communications [PDF]

Third International Conference on Applications of Optics and Photonics, 2017
The ability to use resonant tunneling diodes (RTDs) as both transmitters and receivers is an emerging topic, especially with regards to wireless communications. Successful data transmission has been achieved using electronic RTDs with carrier frequencies exceeding 0.3 THz. Specific optical-based RTDs, which act as photodetectors, have been developed by

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

Advanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...
