  基于掺杂剂选择性迁移到液态金属界面的二维材料掺杂工艺

  摘要：

  在半导体的掺杂过程中引入微量杂质仍然是电子行业的技术挑战。通过利用液态金属界面的选择性富集和收集掺杂的金属氧化物半导体层，可以降低工艺的复杂性，并可以实现对结果的高度控制。在这里，提出了一种用于制备掺杂二维半导体片的自然过滤机制，该机制基于体中金属元素的不同迁移趋势，以竞争富集界面。作为一个模型，采用散装中不同重量比的 Sn 和 Bi 的液态金属合金来收集 Bi 2 O 3掺杂的 SnO 纳米片。在该模型中，即使在本体中 Bi 浓度非常高的情况下，Sn 也比 Bi 更倾向于占据 Bi-Sn 合金的表面位点。这为创建具有严格控制的 Bi 2 O 3掺杂剂的SnO 2D 薄片提供了机会。例如，展示了如何使这种纳米片对还原和氧化环境气体具有选择性。这里展示的过程为​​电子行业未来的合成和制造过程提供了重要的机会。

Herein, the first synthesis of homogeneous Sn1−xBix alloy nanoparticles (x up to 0.20) with native Bi‐doped amorphous SnOx shells for efficient CO2 reduction is reported. The Bi‐SnOx nanoshells boost the production of formate with high Faradaic efficiencies (>90%) over a wide potential window (−0.67 to −0.92 V vs RHE) with low overpotentials, outperforming

  工程学上新颖的基于锡的双金属材料可以提供引人入胜的催化性能，以促进电化学CO 2的还原。在本文中，第一合成均匀的Sn 1- X的Bi X合金纳米颗粒（X与天然Bi-掺杂至多0.20）无定形的SnO X壳用于有效CO 2减少的报道。Bi-SnO x纳米壳可在宽的电势范围内（相对RHE为-0.67至-0.92 V）对法拉第效率高（> 90％）的甲酸盐进行生产，且电势低，优于目前的氧化锡催化剂。源自Sn 0.80 Bi的最新Bi-SnO x纳米壳0.20合金纳米粒子具有74.6 mA cm -2的大分电流密度和95.8％的高法拉第效率。详细的电催化分析和相应的密度泛函理论计算同时表明，将Bi原子掺入Sn物种可通过抑制H 2和CO的形成促进甲酸的产生。

  Abstract The equiatomic SnBi alloy was studied by X-ray angular-dispersive diffraction using a diamond anvil cell up to a pressure of 15 GPa. The first transformation at 1.5 GPa from the eutectic phase mixture (Sn + Bi) to a single phase state (X-phase) confirms earlier work. This is followed upon an increase in pressure to 10.5 GPa by a new transformation to a body centered cubic, bcc, structure. All transformations

  Studying and understanding the dendritic growth process is a challenging topic related to liquid-solid phase transition, as it helps to predict the final microstructure controlling the solder properties. In a specific case of the design of Sn-Bi and Sn-Bi-Cu alloys, the solidification microstructures and corresponding electrical and elastic properties were studied with and without permanent magnetic stirring (PMS), as their influence on the growth morphology of dendrites is not yet fully assessed to date. We use pulse echo overlap (PEO) method for measuring the polycrystalline bulk modulus K, Young's modulus E, shear modulus G, Poisson ratio v and hardness H. The PMS-driven flow caused a disruption of the columnar beta-Sn dendrites and columnar-to-equiaxed transition (CET). Such behavior is believed to evolve from dendrite fragmentation, arises through complex hyper-branched morphologies at the origin of Lorentz force and Seebeck effect that acting on the melt. Both the hardness and elastic modulus are increased as the Poisson's ratio decreased. Moreover, the Pugh ratio clarified the ductility behavior of the alloy samples, while Poisson's ratio and electrical resistivity display slight decrease in the ionic contribution with applying PMS and/or Cu content. These results open new ways to predict the final microstructure controlling the dendritic growth in metallic alloys. (C) 2018 Elsevier B.V. All rights reserved.

  In this paper, the impact of cooling rate on solidification microstructures of Al75Bi9Sn16 alloy was studied for obtaining AleBieSn core-shell organizations by SEM under normal casting conditions. The results show that the core-shell structure is composed of SneBi-rich core and Al-rich shell and outermost thin layer of SneBi phase when Al75Bi9Sn16 alloy melt is cast in a copper mold; when Al75Bi9Sn16 alloy melt is cast in sand mold, alloy does not form the typical core-shell structure.
