Abstract Solution‐processed PbS colloidal quantum dots (CQDs) are promising optoelectronic materials for next‐generation infrared imagers due to their monolithic integratability with silicon readout circuit and tunable bandgap controlled by CQDs size. However, large‐size (diameter >4 nm) longer shortwave‐infrared photodetection consist mainly of {100} facets incomplete surface passivation unsatisfied stability. Here, it is reported that perovskite‐bridged CQDs, in which the epitaxially...
Combining information from multispectral images into a fused image is informative and beneficial for human or machine perception. Currently, multiple photodetectors with different response bands are used, which require complicated algorithms systems to solve the pixel position mismatch problem. An ideal solution would be pixel-level fusion, involves using same photodetector circumventing Here we presented potential of fusion utilizing colloidal quantum dots photodiode array, broadband range...
PbS colloidal quantum dot (CQD) infrared photodiodes have attracted wide attention due to the prospect of developing cost-effective imaging technology. Presently, ZnO films are widely used as electron transport layer (ETL) CQDs photodiodes. However, ZnO-based devices still suffer from problems large dark current and low repeatability, which caused by crystallinity sensitive surface films. Here, we effectively optimized device performance photodiode via diminishing influence adsorbed H2O at...
Abstract Lead sulfide (PbS) colloidal quantum dot (CQD) photodiodes integrated with silicon‐based readout circuits (ROICs) offer a promising solution for the next‐generation short‐wave infrared (SWIR) imaging technology. Despite their potential, large‐size CQD pose challenge due to high dark currents resulting from surface states on non‐passivated (100) facets and trap generated by fusion. In this work, we present novel approach address issue introducing double‐ended ligands that...
Small-size $\mathrm{Pb}\mathrm{S}$ colloidal quantum dots (CQDs) have achieved excellent performance in photoelectric conversion devices through the ligand-exchange method of mixed lead-halide passivation. However, with increase CQD diameter, proportion (100) facets on surface increases and original ligand cannot passivate completely, which will introduce deep defects deteriorate device performance. Here, we demonstrate an excessive ${\mathrm{Pb}\mathrm{Br}}_{2}$ concentration strategy to...
This study investigates the influence of accumulative roll bonding (ARB) cycles on microstructure and room temperature (RT) mechanical properties AT31/ATX3105 magnesium (Mg) alloy composite sheet. It is observed that, as number rolling passes increases, interface between ATX3105 AT31 layers exhibits stronger bonding. Furthermore, after five ARB treatment, grain sizes are refined to ∼5.1 μm ∼4.2 μm, respectively. With increasing passes, strength sheets gradually increased, while their...
In order to study the effect of crushing process on fine separation reclaimed asphalt pavement (RAP) and mechanical properties cement-stabilised aggregate mixed with RAP, four processes, namely small mesh hammer crushing, jaw double roller were used separate from in RAP materials. The grading characteristics agglomeration condition material was investigated. aggregates prepared analysed for their micro-morphology using materials obtained separation. relationship between RAP-added basis...
Low-dimensional semiconductors have been considered excellent materials to construct photodetectors for infrared detection with an easy process and compatibility but suffer from low detectivity mainly owing the poor light absorption of ultra-thin body. Here, we demonstrate a thin film transistor (TFT) based short-wave photodetector consisting carbon nanotube (CNT) TFT gated by PbS colloidal quantum dots (CQDs) heterojunction. The thick CQDs' efficiently absorbs then excites separates...
Lead sulfide (PbS) colloidal quantum dot (CQD) photodetectors (PDs) are promising devices for low-cost, high-performance, and large-area infrared imaging. To achieve commercial applications, it is necessary not only to further improve performance but also high stability. In this study, the uncontrolled migration of Au element into PbS CQD layers was identified. An interface passivation approach employed, which involved implementation a self-assembled island-like LiF interfacial layer between...
Solution-processed colloidal quantum dots (CQDs) photodiodes are compatible for monolithic integration with silicon-based readout circuit, enabling high-performance and low-cost infrared imaging. However, operation stability of CQDs has rarely been explored, which is one the main obstacles imaging commercialization. Here, we reveal that performance deterioration under strong electric field at high temperature mainly attributed to ion migration in film, clearly clarified by aging...
<h3>Objectives</h3> Chronic β1-adrenergic receptor (β1-AR)-calcium/calmodulin-dependent protein kinase II (CaMKII) activation leads to Ca<sup>2+</sup> handling disturbances and adverse cardiac remodeling. We have previously demonstrated that insulin treatment exerts anti-apoptotic prosurvival effects on myocardial ischemia/reperfusion. This study attempted determine whether influences the prolonged ischemic remodeling function underlying mechanisms. <h3>Methods</h3> Myocardial infarction...
<h3>Objectives</h3> Primary reperfusion therapies, including percutaneous coronary intervention (PCI) and thrombolysis, are the standard of care for treating myocardial infarction (MI). Paradoxically, however, return blood flow can also result in additional damage complications, referred to as injury. In ischemic/reperfused (I/R) heart, Ca2+/calmodulin-dependent protein kinase II (CaMKII) activation has been implicated triggering apoptotic signaling. We have previously found that insulin...
