Quantum dots (QDs) have gained significant interest in optoelectronic devices due to their excellent properties. Single-QD materials limit the high performance of photodetectors (PDs). The PDs is enhanced by combining two dissimilar form a heterostructure. responsivity vis–NIR photodetector based on Ag2S/CsPbBr3 heterojunction presented this work. Using CsPbBr3 QDs as first absorption layer and Ag2S second layer, bipolar carrier transporting channel was built. This layered arrangement can...
This review article summarizes the recent advances of F-DLC films in deposition mechanisms, desirable mechanical and prominent tribological properties.
Platinum diselenide (PtSe2) has been exploited for visible and infrared photodetectors due to its tunable electrical photoelectric properties determined by a layer-dependent band gap. We investigated the photoconductive mechanism of few-layer (3 nm) PtSe2 field-effect phototransistor (FEPT) under illumination lasers. The FEPT shows ambipolar characteristics modulated gate voltage with mobility 1496.7 cm2 v–1 s–1 (electron) 1410 (hole) at VDS = 0.16 V. Both positive photoconductivity (PPC)...
Surface energy is essential to the friction properties of materials, but until now investigating scope for DLC films has still been narrow. In this paper, we try expand surface their limits by modification and study influence on properties. case, not only control also manipulate that counter balls, using piranha etching octadecyltrichlorosilane (OTS) modification. The compositions, wettabilities balls were investigated. results indicate energies can be adjusted successfully in ranges 31.2...
Coal measure gas (also known as coal-bearing unconventional gas) is the key field and development direction of natural in recent years. The exploration evaluation coal (coalbed methane, shale tight sandstone from single coalbed methane has greatly expanded space resource evaluation, which positive significance for realizing comprehensive utilization resources, maximizing benefits promoting innovation oil geological theory technological advances development. For first time, Yangmeishu...
Lotus-leaf-like superhydrophobic surfaces have been prepared simply by surface texturing of porous silicon films with capillary stress and the mechanism was studied in detail.
In this study, a kinematic calibration method is proposed. The selects the optimal measurement poses based on observability index O1, and used for six-hardpoint positioning mechanisms, which can identify compensate parameter errors of mechanism. derived error model. order to improve problem that noise affects accuracy, proposed specific effectively improving accuracy. reason using O1 we compared performance five indices through simulation, results show has highest achieve pose selection...
The ovaries are one of the first organs that undergo degenerative changes earlier in aging process, and ovarian is shown by a decrease number quality oocytes. However, little known about molecular mechanisms female age-related fertility decline different types cells during aging, especially goats. Therefore, aim this study was to reveal driving goats at single-cell resolution. For time, we surveyed transcriptomic landscape over 27,000 from newborn, young goats, identified nine cell with...
Abstract Perovskite quantum dots (QDs) and organic materials have great research potential in the field of optoelectronic devices. In this paper, MEH-PPV/CsPbBr 3 heterojunction photodetectors (PDs) are prepared by spin coating method based on good photoelectric properties CsPbBr perovskite QDs MEH-PPV. The improves energy level arrangement, can passivate surface defects MEH-PPV films to achieve effective charge separation transfer, thus inhibiting dark current improving performance device....
Two-dimensional materials have excellent optoelectronic properties and great significance in the field of photodetectors. We prepared a thin film photodetector based on bismuth telluride (Bi2Te3) topological insulator using dual-temperature-zone vapor deposition technology. Due to high-quality lattice structure Bi2Te3 uniform dense surface morphology film, device exhibits photoelectric response Vis–NIR spectral range. Under 405 nm illumination, responsivity is 5.6 mA/W, specific detectivity...
Ultraviolet–visible–near-infrared broad-band PDs have attracted great attention for imaging systems and optical communications. Previous UV–NIR mainly worked in a single band. dual-modal detectors, which maintain greater light response through nonlinear absorbance the second mode, remain to be explored. Here, CsPbI2Br dual-mode PD is reported first time. The absorption, phase stability, chemical stability of are enhanced by CsBr H2O. device shows (UV–vis)/NIR absorption one-photon two-photon...
Ag2S quantum dot (QD) photodetectors (PDs) have attracted a lot of attention in the field imaging system and optical communication. However, current PDs mainly works near-infrared band, its detection ability visible band remains to be strengthened. In this paper, we used poly(3-hexylthiophene) (P3HT) with high carrier mobility QDs construct heterojunction PD. Stronger absorption blends polymer P3HT compared single QDs. The spectra show that Ag2S/P3HT has strong light peak at 394 598 nm....
