Abstract Anion exchange is an effective strategy to regulate the composition and optoelectronic properties of perovskite quantum dots (PQDs). Though promising, it more desirable synthesize PQDs avoid decrease photoluminescence yield (PLQY). Herein, we developed a ligand mediated anion approach, in which phase transition from CsPbBr 3 QDs CsPbI was observed with introduction N‐Acetyl‐ l ‐cysteine (NAC) 1,3‐dimethylimidazolium iodide (DMII) aqueous solution solution. NAC expected create...
Two-dimensional (2D) Ruddlesden–Popper perovskites have demonstrated significant potential in high-performance optoelectronic devices due to their exceptional properties and remarkable stability. However, research on photodetection 2D perovskite/PdSe2 nanosheet heterojunction structures remains limited. In this work, a stable photodetector with high responsivity based heterostructure of perovskite (PEA)2PbI4 PdSe2 nanosheets is demonstrated. The device performance reveals that photodetectors...
Abstract Optoelectronic logic gates (OELGs) are considered a promising alternative to traditional electronic gates, thanks their high computational speed and low power consumption. Meanwhile, there enormous challenges including complex structures single‐function. In this study, the optoelectronic gate device is prepared merely through single Cs 3 Bi 2 Br 9 photodetector. The bidirectional photoresponsive behavior of exhibited under bias voltages modulated by change current level. five...
Phase locking has been demonstrated in fiber lasers coupled to a common resonator containing spatial filter. The phase-locked mode is highly stable despite the phase variations individual elements caused by thermal and mechanical effects. ability maintain attributed self-adjusting process, which can be found only systems with combination of high gain, long length, low Q, broad gain bandwidth, all met laser arrays.
We report the use of photoacoustic signals originating from an optically absorptive target as feedback for shaping incident wavefront to increase optical energy density at delivered through a diffusive medium.
Waveguide taper, a key component in the photonic integrated circuit (PIC), enables on-chip mode conversion, but large-footprint tapers are detrimental to PIC, which desires compact and efficient devices. Polarization sensitivity also limits applications involving orthogonal modes. In this work, we design an polarization-insensitive ultra-short MMI-based waveguide through spreading principle self-image principle. The proposed taper is 26.3 µm long, one order of magnitude shorter than standard...
The complete Auger decay of ${\mathrm{Rb}}^{+}(3{d}^{\ensuremath{-}1})$ including single and double processes is investigated using the distorted wave approximation. direct was calculated by separating knock-out shake-off mechanisms. For $3{d}^{\ensuremath{-}1}$ hole state, it generally believed that dominant channels should be levels belonging to configurations $[1{s}^{2}2{s}^{2}2{p}^{6}3{s}^{2}3{p}^{6}3{d}^{10}]4{s}^{2}4{p}^{4}5s$, $4s4{p}^{5}5s$, $4{s}^{0}4{p}^{6}5s$. Here we predict...
In this work we investigated the competition between local Auger decay and core-level interatomic Coulombic (ICD) processes in core ionized rare-gas dimers. We computed respective partial widths for $4d$ vacancy ${\mathrm{Xe}}_{2}$, XeKr, XeAr, as well $3d$ ${\mathrm{Kr}}_{2}$. found that efficiency of ICD is strongly increased with decreasing distance energy transfer step. The ICD-to-Auger ratio Franck-Condon region, where occurs, at most 0.26%. However, it reaches a few percentage points...
Microwave absorption materials have been increasingly attracting our attention as an effective method of mitigating electromagnetic pollution. Among these materials, molybdenum carbide/carbon (Mo<sub>2</sub>C/C) composites gradually emerged a prominent candidate in the field microwave owing to their lightweight characteristics, chemical stability, and exceptional dielectric properties. In this study, significant advancements research on Mo<sub>2</sub>C/C are reviewed, encompassing binary...
Abstract Biological cells are almost never truly spherical, even in the absence of an obvious cause that disrupts cell's symmetry. Using rather simple energy considerations, we show though all real biological subject to a completely radial electric field along cell membrane, spherical shape is unstable under most practical situations. This result appears have been overlooked literature.
Polarization dependence in integrated silicon photonics has a detrimental effect on the manipulation of quantum state with different polarizations technology. Those limits have profound implications for further technological developments, especially photonic internet. Here, we propose polarization-independent Mach–Zehnder interferometer (MZI) structure based 340 nm-thick silicon-on-insulator (SOI) platform. The MZI facilitates low loss, broad operating bandwidth, and large tolerance...
