Novel seed-assisted synthesis of indium tin oxide submicro-cubes and their resistivity

《化学科学与工程前沿（英文）》 2023年第17卷第5期页码 557-569 doi: 10.1007/s11705-022-2249-9

摘要： Indium tin oxide films, an important n-type semiconductor oxide, show great prospects in optoelectronic device applications. Consequently, as a key raw material of targets for sputtering films, it is important to prepare low-resistivity indium tin oxide powders. Herein, low-resistivity indium tin oxide submicro-cubes are synthesized by a seed-assisted coprecipitation method. The effects of seed content, In³⁺ concentration, aging time, reaction temperature and calcination temperature on resistivity were investigated by single factor and orthogonal experiments. To ensure reliability and reproducibility of data, each experiment was repeated three times and resistivity of each sample was measured three times to obtain average value. The results indicated that optimal sample was matched with cubic phase In₂O₃. The single-crystal indium tin oxide particles exhibited a regular cubic shape with a size of nearly 500 nm and low resistivity of 0.814 Ω·cm. Compared with particles prepared by the conventional coprecipitation method, indium tin oxide submicro-cubes showed good dispersion. The presence of seed particles provided nucleation sites with lower energy barriers and promoted formation of submicro-cubes. The face-to-face contact among particles and good dispersion contributed to electron transfer, resulting in lower resistivity. The seed-assisted synthesis provides a novel way to prepare low-resistivity indium tin oxide submicro-cubes.

利用人工源超低频电磁波监测地震的试验与分析

赵国泽,陆建勋

《中国工程科学》 2003年第5卷第10期页码 27-33

摘要：

由人工产生大功率超低频（SLF）电磁波可以在地面很大范围的许多测点同时测量该信号，利用它可以研究地下电阻率结构和空间电磁场；研究地震等引起的电磁场异常变化；探测地壳结构和地下资源，具有广阔的应用前景和发展潜力。在北京等地区的观测表明,SLF信号的功率谱密度超过天然场源信号数倍以上，所得到的视电阻率数据精度远高于天然源方法，并有长时间的稳定性。在试验测量期间距测点约120 km发生的迁安4.2级地震与观测的电磁场异常和视电阻率的变化有较好的对应性,对产生这些变化的可能的成因机制进行了分析和探讨。

摘要：

研究了用于舰船管系异种金属绝缘的石棉橡胶纤维垫片和环氧垫片在海水、碱溶液（10 % NaOH溶液）、酸溶液（10 % H2SO4溶液）和重油中浸泡后，其体电阻率和面电阻率随浸泡时间的变化规律。实验结果显示，石棉橡胶纤维垫片在酸、碱溶液中浸泡两个月后，其湿态电阻降低到102欧姆（或欧姆?厘米）量级，在海水中的电绝缘有效期约为4个月，环氧垫片的湿态电阻可保持为104~6欧姆（或欧姆?厘米）量级，环氧材料组成的垫片其绝缘性能远好于石棉橡胶纤维垫片的绝缘性能。

摘要：

Achieving historically anticipated improvement in the performance of integrated circuits is challenging, due to the increasing cost and complexity of the required technologies with each new generation. To overcome this limitation, the exploration and development of novel interconnect materials and processes are highly desirable in the microelectronics field. Molybdenum (Mo) is attracting attention as an advanced interconnect material due to its small resistivity size effect and high cohesive energy; however, effective processing methods for such materials have not been widely investigated. Here, we investigate the electrochemical behavior of ions in the confined nanopores that affect the electrical properties and microstructures of nanoscale Mo and Mo–Co alloys prepared via template-assisted electrodeposition. Additives in an electrolyte allow the deposition of extremely pure metal materials, due to their interaction with metal ions and nanopores. In this study, boric acid and tetrabutylammonium bisulfate (TBA) were added to an acetate bath to inhibit the hydrogen evolution reaction. TBA accelerated the reduction of Mo at the surface by inducing surface conduction on the nanopores. Metallic Mo nanowires with a 130 nm diameter synthesized through high-aspect-ratio nanopore engineering exhibited a resistivity of (63.0 ± 17.9) μΩ·cm. We also evaluated the resistivities of Mo–Co alloy nanowires at various compositions toward replacing irreducible conventional barrier/liner layers. An intermetallic compound formed at an Mo composition of 28.6 at%, the resistivity of the Mo–Co nanowire was (58.0 ± 10.6) μΩ·cm, indicating its superior electrical and adhesive properties in comparison with those of conventional barriers such as TaN and TiN. Furthermore, density functional theory and non-equilibrium Green’s function calculations confirmed that the vertical resistance of the via structure constructed from Mo-based materials was 21% lower than that of a conventional Cu/Ta/TaN structure.
