Spatter rate is impacted by the beam oscillating effect; as frequency increases, Nv and FRL weaken while Mk increases, resulting in more spatter. Cai et al. [26] with a welding machine used a 10 kW fiber laser with a 400 mm focal distance and a wavelength of 1070 nm. A high-speed vi...
The surface roughness and crystal quality of our AlN epilayer were respectively characterized by an atomic force microscope and an X-ray diffraction scan, indicating a root-mean-square roughness of 0.2 nm in 1 × 1 μm2 region and an FWHM linewidth of ~46 and 1000 arcsec ...
The position of the first peak in the radial distribution functions is determined as 0.143 nm in both cases, which is in good agreement with the distance between the nearest atoms of 0.142 nm. However, the ratios of the atomic density in the nearest radius to that in the second nearest ...
Structural, electrical, and optical properties of atomic layer deposition Al-doped ZnO films Al-doped ZnO (AZO) films of100nmthickness with various Al doping were prepared at150°Cby atomic layer deposition on quartz substrates. At low Al doping, t... P Banerjee,WJ Lee,KR Bae,... - 《...
atomic complexes enriched with Sc and Cu, high-angle annular dark-field STEM (HAADF-STEM) has been applied in the AlCuSc-C alloy. As shown in Fig.4g–i, a high-density nanosized (~1 nm with a volumetric number density of ~2.0 × 1024 m−3) features with significantly ...
The structure of the anodized aluminum oxide layer is nanoporous, formed by a hexagonal array of cells with cylindrical pores with a diameter of 25 nm to 0.3 μm and depth up to 100 μm27. The combination of chemical etching and anodization processes is expected to produce the combination ...
In order to achieve energy convergence, the wave functions in the interstitial region were expanded in plane waves with a cut-off Kmax = 9/RMT, where RMT denotes the smallest atomic sphere radius and Kmax gives the magnitude of the largest K vector in the plane wave expansion. The RMT are...
This supposition has been recently proved by the detection of atomic aluminum during ignition of Al nanoparticles with d = 80 nm behind the reflected shock wave [16]. The particles with larger size can be in a liquid phase, and, frequently (see, for example, [17]), the formation of ...
We used the t-distributed stochastic neighbor embedding (t-SNE) method to map local atomic environments into two dimensions. Radial neighbor regression (RNR) is used to color the average property within a radius of a given point in the 2D embedding space. a Active learning iteration at which ...
The AZO thin film is deposited successfully by atomic layer deposition (ALD). 50 nm-thick AZO film with high uniformity is checked by scanning electron microscopy. The element composition of the deposited film with various aluminum dopant concentration is analyzed by energy-dispersive X-ray ...
