6) vapor-solid-solid mechanism 气-固-固机制补充资料:气液固反应器 分子式:CAS号:性质:又称气液固反应器。即反应系统中存在气液固三相的反应器。可分为三类(1)气液固三者都是反应物或产物,如氨水与二氧化碳生成碳酸氢铵固体的碳化塔。(2)气液为反应物或产物,固相为催化剂,如苯在镍催化剂上液相加氢制...
To do so, the growth mechanism will be discussed in this paper and the influence of the size of the metallic nanocluster starting point, referred to later as "size effect," will be studied. Among many of the so-called size effects, a tremendous decrease of the melting point of the ...
The second mechanism, vapor-liquid-solid (VLS), has been used widely for explaining the growth of columnar crystals of silicon in the process of chemical vapor deposition in the presence of liquid gold drops on the substrate.doi:10.1016/b978-0-12-804173-4.00168-xAlexander S. Mukasyan...
In contrast to the previous growth mechanism for h-BN, the isothermal growth procedure on an active melted Fe–B alloy greatly improved the uniformity, crystallinity and smoothed surface of the h-BN layers. It may suppress the formation of thick h-BN flakes induced by cooling-induced ...
3C-SiC Heteroepitaxial Growth by Vapor-Liquid-Solid Mechanism on Patterned 4H-SiC Substrate Using Si-Ge Melt In this work, we report on the use of patterned 4H-SiC(0001) substrates for the heteroepitaxial growth of 3C-SiC by vapor-liquid-solid (VLS) mechanism usin... D Tournier,D Carole,...
We report on the heteroepitaxial growth of 3C-SiC layers by a vapor–liquid–solid (VLS) mechanism on various α-SiC substrates, namely, on- and off-axis for both 4H- and 6H-SiC(0001), Si and C faces. The Si-Ge melts, in which the Si content was varied from 10 to 50 atom%, ...
Silicon nanowires have been synthesized by a simple process using a suitable support containing silica and carbon microspheres. Nanowires were grown by thermal chemical vapor deposition via a vapor-liquid-solid mechanism with only the substrate as silicon source. The curved surface of the microsized sp...

Vapor-liquid-solid mechanism of single crystal growth. Encapsulation of iron(III) oxide in carbon nanotube bundles using pulsed laser ablation From the enlarged SEM image (Figure 1(b)) we can see clearly the droplet of Au nanoparticles on the apex of each nanowire, indicating the vapor-liquid...
