    Description

    PhD students Mr. Hongti ZHANG (first author) and Mr. Shang XU who are under the supervision of Dr. Yang LU, and Mr. Qiaobao ZHANG, under the supervision of Dr. Kaili ZHANG, recently published a paper titled “Approaching the ideal elastic strain limit in silicon nanowires” in Science Advances together with their supervisors, Professor C. S. Lee from the Department of Physics and Materials Science, and other collaborators from the Massachusetts Institute of Technology; University of California, Los Angeles; Xiamen University; and IBM Research Centre. The recent research led by Dr. Lu has shown that silicon nanowires can be stretched above 10% elastic strain, several times higher than that of previous findings. A few samples even reached 16%, very close to their theoretical elastic limit. This groundbreaking discovery will likely bring about revolutionary changes to flexible electronics and medical equipment for the well-being of society.

    Dr. Lu and his team have been recently awarded about HK$700,000 from the Research Grants Council of Hong Kong for conducting further research on “Elastic Strain Engineering” of the nanosized silicon. Published by the American Association for the Advancement of Science (AAAS), Science Advances aims to publish significant, innovative original research that advances the frontiers of science and extends the standards of excellence established by Science.

      Description香港城市大學（城大）機械及生物醫學工程學系領導的一項研究發現，矽納米線（silicon nanowire）的拉伸彈性可達一成以上，較過去的發現高出數倍，個別樣本的拉伸彈性更達16%，近乎矽理論上的彈性極限（約17%至20%）。這突破性發現將大大推動柔性電子學發展，並革新醫療儀器科技，造福社會。
      這項研究名為「實現矽納米線的理論彈性極限」，8月在美國科學促進會出版的學術期刊《科學進展》上發表，城大機械及生物醫學工程學系博士生張洪題為論文第一撰寫人，他的導師是該學系助理教授陸洋。

    • TitleStretching the limit of silicon nanowires for next-generation electronics
      Media name/outletArs Technica

      Date27/08/16
      DescriptionFlexible electronics, which could be used to control flexible robots, depend on the ability to produce electrical circuits that can be repeatedly stretched and bent while remaining operational. Silicon is obviously one of the most important building blocks of modern electronics, but even when it's shaped into wires, it isn't very stretchy.
      Recently, an international team of scientists and engineers has directly probed the elastic strain limit of single-crystalline Si nanowires. The team found that stretching the Si nanowires almost to their theoretical limit is possible.

      DescriptionDer Halbleiter Silizium bildet die Grundlage aller gängigen Computerchips. Doch als kristallines Material ist es spröde und bruchempfindlich. Dennoch gelang es nun einer chinesisch-amerikanischen Forschergruppe, winzige Nanodrähte aus Silizium wiederholt zu dehnen. So elastisch wie Gummi waren sie zwar nicht, doch immerhin konnten einzelne Drähte um bis zu 16 Prozent gestreckt werden. Dieser Erfolg soll nun den Weg bereiten, um Silizium verstärkt in flexiblen elektronischen Bauteilen zu nutzen. Damit wären leistungsfähigere Bildschirme und Elektronikmodule für intelligente Kleidung und bessere Sensoren in der Medizintechnik möglich.
