In the early stages of architectural design, architects convert initial ideas into concrete design schemes, which heavily rely on their creativity and consume considerable time. Therefore, generative methods based artificial intelligence are promising for such tasks. However, effectively communicating concepts to machines is challenging. To address this challenge, paper proposes a novel cross-model approach using textual descriptions assist architects, comprising concept extraction module an...
Zinc-blende CrSb (zb-CrSb) layers with room-temperature ferromagnetism have been grown on (In,Ga)As buffer epitaxially prepared (001) GaAs substrates by molecular-beam epitaxy. Compared the typical thickness [2–3 ML (ML denotes monolayers)] of zb-CrSb directly GaAs, has increased largely; maximum can be up to ∼9 ML. High-resolution cross sectional transmission electron microscopy images show that layer is combined without any dislocations at interface.
A metal-source flow-rate modulation epitaxy method is reported to enhance the hole concentration of Mg-doped AlGaN grown by metal organic chemical vapor deposition. The p-type (Al content 0.43) increased 2.3 × 1017 cm−3 at room temperature this method, which about ten times higher than that conventional growth. resistivity was found be as low 12.7 Ω·cm. Furthermore, effective acceptor activation energy (EA) in films 0.32–0.43) determined 20–22 meV, several smaller EA p-GaN. Secondary ion...
Carrier transport and electrical properties are relevant to the performance of semiconductor materials photovoltaic devices. In recent years, various kinds high-resolution luminescence-based methods have been proposed image these properties. Lock-in carrierography (LIC), as a dynamic photoluminescence-based method, has advantages self-calibration, higher signal noise ratio than dc or transient modalities, high-frequency imaging ability. At present stage development, LIC evolved into homodyne...
AlGaN/AlN superlattices (SLs) are key building blocks for vertical emitting devices, especially in the deep UV spectral range. Abrupt interfaces of 30-pair (6.6 nm/3.3 nm) SLs with an average Al composition 55.3% have been grown by NH3 flow-rate modulation epitaxy (FME). The interface and surface morphology can be largely improved using this growth technique due to enhancement migration atoms. Moreover, basal stacking faults at observed high resolution transmission electron microscopy. A...
We studied the effect of oxygen on growth quality diamond epitaxial layers. After is added during layer, as thickness layer increases, full width at half maximum rocking curve (004) plane increases continuously, and, in addition, intensities both Raman peaks and free exciton emission decrease continuously. These experimental results demonstrate that degrades. The strong etching OH radical groups plasma epilayers leads to degradation their crystallinity.
In this paper, the effects of thermal annealing (TA) were studied by theoretical calculation and experiment. The was based on Masafumi's model dislocation movement, modified with stress lattice-mismatch in HgCdTe/CdTe/Si(211) heterostructure. As indicated, temperature holding time TA had great effect reduction, while less improvement epilayer thickness growth orientation. Upon result calculation, cycle (TCA) experiments performed under different conditions, which fit properly. reduction...
More than half of heart failure (HF) cases are classified as with preserved ejection fraction (HFpEF) worldwide.

The recent research results on molecular beam epitaxy of HgCdTe CdZnTe were presented. substrates mounting process, under protective atmosphere, was essential to avoid substrate oxidation. It demonstrated by in-situ reflection high-energy electron diffraction (RHEED), during deoxide process. Concerning the poor thermal conductivity CdZnTe, good uniformity is hard obtained, compared with GaAs or Si. found that crystal quality HgCdTe/CdZnTe strongly temperature dependent. According morphology,...
In order to utilize the non-destructiveness and quickness of spectroscopic reflectometry based technique for red, green, blue (RGB) color filter thickness measurement, refractive indices (n's) extinction coefficients (k's) RGB coatings need be precisely determined. This work demonstrates use variable angle ellipsometry (VASE) measuring n k values coatings. The each thin film is determined in its respective transparent band. optical constants are calculated directly from Fresnel equations at...
Abstract Background In the early stages of coronavirus disease pandemic, anti-malarial drug hydroxychloroquine (HCQ) and antibiotic azithromycin (AZM) were widely used as emerging treatments. However, controversial cardiac toxicity results obtained from clinical trials epidemic studies suggest that cardiotoxicity these two drugs should be re-evaluated. present study, we aimed to assess impact a short course AZM or HCQ + combination treatment on ECG function in healthy guinea pigs. Methods...
Soft X-ray interference lithography is a new micro-nano fabrication technology which uses multi beam soft to form field expose photoresist. Due the photochemical sensitivity of photoresist, required fine patterns can be transferred from mask substrate after exposure, development and etching. It also technique frequency doubling period. In this paper, change line edge roughness pattern before photoresist etching studied. The results show that structure better than etched nano 2.20 nm, two...
