Engineering grad student’s work leads to award-winning paper


<p>Three ASU researchers are among co-authors recently awarded a top international prize for outstanding science papers.</p><separator></separator><p>The Van Duzer prize is given annually by the Institute of Electrical and Electronic Engineers (IEEE), one of the world&#39;s leading associations supporting technological advancement. The award recognizes what the organization considers the best paper published in 2006 in its Transactions on Applied Superconductivity journal.</p><separator></separator><p>Work led by Lei Yu, a graduate student in a research group in ASU&#39;s School of Materials led by professor Nathan Newman, resulted in the paper “Incorporation of a Frequency-Dependent Dielectric Response for the Barrier Material in the Josephson Junction Circuit Model,” detailing discoveries that hold potential for a major impact on advances in electronics.</p><separator></separator><p>Yu&#39;s ASU co-writers include Newman, director of the Center for Solid State Science and research director for School of Materials , and John Rowell, a visiting professor and member of the National Academy of Engineering and National Academy of Science.</p><separator></separator><p>The fourth author is Theodore Van Duzer, a longtime distinguished engineering researcher, a member of the National Academy of Engineering and faculty member at the University of California-Berkeley. The Van Duzer prize is named for him.</p><separator></separator><p>“Lei Yu was the driving force for the article,” Newman says. “It is a phenomenal achievement that his graduate work led to such a major award. That is extremely rare, so it&#39;s all the more impressive.”</p><separator></separator><p>The team&#39;s paper presents a mathematical model for a type of Josephson junction. As transistors are to semiconductor technology, Josephson junctions are the fundamental device of superconductive circuit technology – also called SC technology.</p><separator></separator><p>SC technology could enable the design and fabrication of a new class of digital electronics that operate at speeds 10 to 100 times faster than today&#39;s electronics. It promises a level of performance that can&#39;t be matched by semiconductor technology and could “revolutionize large-scale digital electronic applications,” such as high-performance microprocessors and communication systems, Newman says.</p>
