Abstract High energy consumption and lack of readability under bright sunlight conventional transmissive display technology greatly limit the user experience mobile wearable devices. To solve this issue, a hybrid by overlaying full‐color reflective on top is invented. The key component based tandem switchable all‐dielectric metasurfaces. metasurfaces in large size (average area ≈5 cm 2 ) are invented fabricated low‐cost high‐throughput nanoimprint lithography. Each metasurface formed an...
A memristor-based hybrid analog-digital computing platform enables more energy-efficient and responsive mobile robotics.
Gap plasmonic nanostructures are of great interest due to their ability concentrate light into small volumes. Theoretical studies, considering quantum mechanical effects, have predicted the optimal spatial gap between adjacent nanoparticles be in subnanometer regime order achieve strongest possible field enhancement. Here, we present a technology fabricate structures with resolution, high reliability, and throughput using collapsible nanofingers. This approach enables us systematically...
2-Amino-5-chlorobenzophenone (ACB) with multiple functional groups is adopted to passivate surface defects of perovskite films for achieving efficient and stable PSCs.
Abstract: Dielectric drying methods with microwave (MW) and radio frequency (RF) energy as emerging technologies have drawn much attention from both research community industry over the past decades. When properly applied, MW RF can be efficient of great potential to used for a wide range materials. However there are few reviews that cover d r ying technologies. Such review is timely considering ever increasing interest food in adapting new This paper attends provide comprehensive on uses...
Optical devices with asymmetric transmission have important applications in optical systems, but isolators the modal asymmetry can only be built using magneto-optical or nonlinear materials, as dictated by Lorentz reciprocity theorem. However, power achieved linear materials such metals and dielectrics. In this paper, we report a large-area, nanoimprint-defined meta-surface (stacked subwavelength gratings) high-contrast transmittance visible-to-infrared wavelength range for TM-polarized...
On the surface of perovskite films, large quantities defects are produced during preparation and exposure to air ambience, they key constraints performance solar cells (PSCs). Passivating via organic molecules is an effective approach fabricating efficient stable PSCs. Herein, molecule 3-ethoxy-4-hydroxybenzadehyde (EVL) employed passivate on films. The aldehyde (−CHO) functional group EVL can under-coordinated lead ion (Pb2+) defects, its hydroxyl (−OH) alkoxy (−O–CH2) groups impede...
Background The Coronavirus disease 19 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a threat to human health. Although COVID-19 pandemic finished, some peoples are still suffering from this disease. Herein, we report first case of SARS-CoV-2-associated Guillain-Barré (GBS) presenting as polyneuritis cranialis (PNC) and panautonomic neuropathy (APN) variants, accompanied mild encephalitis/encephalopathy with reversible splenial lesion (MERS)...
Plasmas containing ion beams have various applications both in plasma technology and fundamental research. The beam energy flux are the two factors characterizing properties. Previous studies not achieved independent adjustment of these parameters. In this paper, an ion-beam-background-plasma system was produced with hot-cathode discharge a double device separated by adjacent grids, which ratio (the between total flux) can be controlled independently. It is shown that voltage (i.e., across...
Abstract On the surface and grain boundary of perovskite films there are large quantities defects, which leads to photogenerated carrier nonradiative recombination degrades performance solar cells (PSCs). Surface passivation can suppress detrimental effects defect improve PSCs. Here, an organic molecule, 4‐chloro‐1,8‐naphthalic anhydride (ALS), is adopted passivate defects on (FAPbI 3 ) 0.95 (MAPbBr 0.05 films. The oxygen carbonyl group in ALS provides lone pair electron undercoordinated Pb...

This paper presents an effective approach for silicon nitride plasma dry etching, with low DC-bias (self-bias) and vertical sidewalls. Four factors were studied: capacitively coupled radio frequency power, inductively pressure in the etching chamber, combination of gases. By meticulously controlling these factors, authors successfully achieved anisotropic without argon bombardment, only 34 V rate 40 nm/min. Our new recipe can avoid short-circuits effectively when patterning sub-50 nm thick...
