Dependence of Photoresponsivity and On/Off Ratio on Quantum Dot Density in Quantum Dot Sensitized MoS2 Photodetector

open access: yesNanomaterials, 2020
Non-radiative energy transfer (NRET) from quantum dots (QDs) to monolayer MoS2 has been shown to greatly enhance the photoresponsivity of the MoS2 photodetector, lifting the limitations imposed by monolayer absorption thickness.

Relative uptake capacity of QD-glycine and QD-chitosan.

open access: yes, 2015
Relative uptake capacity is QD uptake capacity of QD-compounds (as QDs μm3 d-1) divided by QD uptake capacity of QD-references. Microbes from control versus N-fertilized plots were added to control versus N-fertilized litter in microbial cages, in a ...

Fluorescence and Cytotoxicity of Cadmium Sulfide Quantum Dots Stabilized on Clay Nanotubes

open access: yesNanomaterials, 2018
Quantum dots (QD) are widely used for cellular labeling due to enhanced brightness, resistance to photobleaching, and multicolor light emissions. CdS and CdxZn1−xS nanoparticles with sizes of 6–8 nm were synthesized via a ligand assisted technique inside

QD floating gate NVRAM using QD channel for faster erasing [PDF]

open access: yesElectronics Letters, 2018
A new pathway to design floating gate quantum dot (QD) non‐volatile RAM (QDNVRAM) cells that possess high‐speed low‐voltage Erase capabilities not possible with conventional floating gate NV memories is presented. This is achieved by directly accessing the QD floating gate layer with an additional drain (D2) during the Erase operation.
