This paper describes how Atomic Layer Deposition (ALD) has evolved over time using a combination of bibliometric, social network, and text analysis. We examined the rate of knowledge production as well as changes in authors, journals, and collaborators, showing a steady growth of ALD research. The study of the collaboration network of ALD scientists over time points out that the ALD research community is becoming larger and more interconnected, with a largest connected component that spans 90% of the authors in 2015. In addition, the evolution of network centrality measures (degree and betweenness centrality) and author productivity revealed the central figures in ALD over time, including new "stars" appearing in the last decade. Finally, the study of the title words in our dataset is consistent with a shift in focus on research topics towards energy applications and nanotechnology.
本文描述了如何通过结合文献计量学、社会网络分析和文本分析的方法，来展现原子层沉积（ALD）技术随时间的发展历程。我们研究了知识产出率以及作者、期刊和合作情况的变化，结果表明ALD研究呈稳步增长态势。对ALD科学家合作网络随时间变化的研究指出，ALD研究群体正变得越来越大且联系日益紧密，在2015年最大的连通分支涵盖了90%的作者。此外，网络中心性指标（度中心性和中介中心性）的演变以及作者的生产力揭示了ALD领域不同时期的核心人物，包括过去十年中涌现的新“明星”。最后，对我们数据集中标题词汇的研究与研究主题向能源应用和纳米技术的转变相一致。
