The effect of a charge trap in the vicinity of the quantum-dot on the charge stability diagram of a single electron transistor [PDF]

AUT Journal of Electrical Engineering
In this article, we explored the effect of a single charge trap on the charge stability diagram of the quantum-dot-based single-electron transistor. We investigated anomalies in the coulomb characteristic diagram, system energy, occupation probabilities,

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

15.13% Sr-doped CsPbI3 quantum dots with near-unity quantum yield via surface ligand compensation

Nano Research
Sr-doping of perovskite quantum dots (QDs) is a promising strategy to reduce Pb content and improve optical performance and stability. However, excessive Sr introduces new defects that degrade photoluminescence quantum yield (PLQY).

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Formation InAs Quantum Dots in a Matrix GaAs in Kinetic Mode for CVD-method [PDF]

Журнал нано- та електронної фізики, 2017
We present the results of theoretical study for the kinetic mode of quantum dot formation in the InAs / GaAs system. The theory is valid at the kinetic stage of quantum dot formation, when the island ensemble remains dilute and thus noninteracting.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

Advanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

The effects of pressure and temperature on the exchange energy of a parabolic quantum dot under a magnetic field

Journal of Taibah University for Science, 2017
The combined effects of pressure and temperature on the energy levels of a parabolic GaAs quantum dot under a magnetic field have been studied. The exact diagonalization method was used to solve the two-electron quantum dot Hamiltonian and to obtain the ...
