西元年：2012 研究人員(中)：莊天明 研究人員(英)：TIEN-MING, CHUANG, M. P. Allan, A. W. Rost, A. P. Mackenzie, Yang Xie, J. C. Davis, K. Kihou, C. H. Lee, A. Iyo, H. Eisaki 研究成果名稱(中)：鐵基高溫超導體之超導能隙異向性研究 研究成果名稱(英)：Anisotropic Energy Gaps of Iron-based Superconductivity from Intraband Quasiparticle Interference in LiFeAs 簡要記述(中)：超導體中，電子會形成庫柏電子對，在晶格中移動時不會產生電阻。來自台、日、英、美的研究團隊，藉由量測鐵基超導體中庫柏電子對的內部電子聯結強度，證實磁 性對高溫超導具有關鍵性的影響。實驗也檢驗此強度與電子移動方向的關聯性，進一步驗證了理論的預測。我們希望未來這類理論可用在檢視及設計更高溫的超導 體。此研究成果發表在「科學」期刊（Science 336, 563 (2012)）。 高溫超導成因已困惑了科學家近三十年。許多人相信藉磁性媒介的電子間交互作用是關鍵。於2008年發現的鐵基超導體 為這個想法提供了另一個有力證據，因為它們的母系化合物像銅基高溫超導體有類似反鐵磁性。但決定磁性在鐵基超導的角色是個複雜問題，因為每個鐵原子有五個電子貢獻磁性。為查明是否電子間磁 交互作用產生超導，必須量測超導能隙異向性。此物理量可顯示庫柏電子對在動量空間中不同方向的鍵結強度。 理論學家們針對以磁性為主的電子配對機制發展出不同的高溫超導理論，並預測符合這些理論的實驗結果將會是如何。研究團隊發現實驗結果吻合理論預測的特徵。本文共同通訊作者院莊天明博士指出「儘管理論學家預測超導能隙異向性的存在，但由於複雜 的電子結構，計算這效應的大小仍是非常的困難。我們的量測結果不僅在定性上與理論預測吻合，並且提供理論學家關鍵資訊以發展定量的高溫超導理論。」 簡要記述(英)：In superconductors, electrons form Cooper pairs and move through the crystal lattice without resistance. By measuring how strongly Cooper pairs are bound together in an iron-based superconductor, scientists from Academia Sinica, the University of St Andrews, Cornell University, the U.S. Department of Energy’s Brookhaven National Laboratory and AIST, Japan, provide direct evidence supporting theories in which magnetism holds the key to this material’s ability to carry current with no resistance. The measurements take into account the directions in which the electrons are traveling, which was central to testing the theoretical predictions, thereby strengthening confidence that this type of theory may one day be used to identify or design new materials with improved properties - namely, superconductors operating at room temperatures. The findings are published in Science 336, 563 on May 4, 2012. High-temperature superconductors have been fascinating to both scientists and engineers since they could carry current with no loss at temperatures as high as 155 K. The hope is that understanding the physics of these compounds will lead to the design of superconductors able to operate at room temperatures, which can be used for energy-saving technologies, such as zero-lose power transmission lines. However, the physics of high temperature superconductivity has confounded scientists over the last 30 years. It is generally believed that the magnetically mediated electron-electron interaction of these materials is the key. When iron-based superconductors were discovered in 2008, this idea received a big boost because their parent compounds exhibit similar magnetic properties as their copper-based counterparts. However, determining that role is a very complex problem. In each iron atom there are five magnetic electrons. In order to find out if the magnetic interactions between electrons are generating the superconductivity, one has to measure what’s called the anisotropic superconducting energy gap, which can tell scientists the bounding strength of Cooper pairs along different directions in momentum space. Their method, multi-band Bogoliubov quasiparticle scattering interference, found the “signature” predicted by magnetism-based pairing theory. "Although theorists predicted the existence of superconducting gap anisotropy, it’s difficult to calculate how large this effect is. Our measurements not only agree with the theoretical prediction but also provide theorists with crucial information towards a more quantified description." said Dr. Tien-Ming Chuang of Academia Sinica. The next step is to use the same technique to determine whether the theory holds true for other iron superconductors. 主要相關著作： M. P. Allan, A. W. Rost, A. P. Mackenzie, Yang Xie, J. C. Davis*, K.
