Effect of diamine treatment on the conversion efficiency of PbSe colloidal quantum dot solar cells [PDF]

, 2009
Polymer-free photovoltaic devices were fabricated via a solution process using PbSe colloidal quantum dots (QDs) and an organic semiconductor (tetrabenzoporphyrin, BP) that can be prepared in situ from a soluble precursor.

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

Advanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

CdSe quantum dots (QDs) were synthesized by a hot-bubbling strategy

IOP Conference Series: Materials Science and Engineering, 2020
Abstract A hot-bubbling strategy was studied to synthesize CdSe quantum dots. The synthetic parameters including temperature and growth time, were studied to show great influence on the optical properties. At the different reaction time CdSe quantum dots could emit fluorescence of different color, ranging from green to red, under the ...

CMOS‐Integrated Synaptic Photoreceptor Chip Inspired by Insect Visual Processing

Advanced Science, EarlyView.
CMOS‐integrated Si QDs/ReS2 synaptic photoreceptor array mimics the parallel processing and wavelength‐selective strategy of insect vision. By combining intrinsic ultraviolet‐violet sensitivity with synaptic plasticity, the chip enables frontend sensory redundancy reduction without external filters, offering a scalable pathway toward lowpower ...

Optical TCAD on the Net: A tight-binding study of inter-band light transitions in self-assembled InAs/GaAs quantum dot photodetectors

, 2013
A new capability of our well-known NEMO 3-D simulator (Ref. Klimeck et al., 2007 [10]) is introduced by carefully investigating the utility of III–V semiconductor quantum dots as infrared photodetectors at a wavelength of 1.2–1.5 μm.

Synthesis of Novel Stable ZnSe Magic‐Sized Clusters and Their Direct Transformation to Quantum Dots

Advanced Science, EarlyView.
We have developed a low‐temperature synthetic approach that enables the fabrication of novel ZnSe MSCs with remarkable thermal stability. These stabilized MSCs serve as efficient precursors that can be readily converted to ZnSe QDs under mild conditions through simple introduction of a selenium source.

Ab Initio Molecular Dynamics of CdSe Quantum-Dot-Doped Glasses

, 2020
We have probed the local atomic structure of the interface between a CdSe quantum dot (QD) and a sodium silicate glass matrix. Using ab initio molecular dynamics simulations, we determined the structural properties and bond lengths, in excellent ...

Phase transitions in quantum dot-Majorana zero mode coupling systems

SciPost Physics Core
The magnetic doublet ground state (GS) of a quantum dot (QD) could be changed to a spin-singlet GS by coupling to a superconductor. In analogy, here we study the GS phase transitions in QD-Majorana zero mode (MZM) coupling systems: GS behaves phase ...
