The Association’s oldest award, the AAAS Newcomb Cleveland Prize, supported by Affymetrix, was established in 1923 with funds donated by Newcomb Cleveland of New York City. The Prize acknowledges an outstanding paper published in the Articles, Research Articles, or Reports sections of Science. Each recipient receives a bronze medal and a share of the $25,000 prize.

The 2005 AAAS Newcomb Prize is awarded to the following authors:

David D. Awschalom, Yuichiro K. Kato, Roberto C. Myers, and Arthur C. Gossard for the research article “Observation of the Spin Hall Effect in Semiconductors,” published 10 December 2004, pp. 1910-1913. At the time of publication, the authors’ affiliation was the Center for Spintronics and Quantum Computation, University of California, Santa Barbara. Currently, Kato is at Stanford University.

This paper shows, for the first time, the spin effects in semiconducting materials induced by electric fields along the length of the material. The authors were able to show that oppositely directed (up- and down-spins) could be induced at the edges, using an elegant optical technique. They then examined possible sources of the effect, showing that it is not the result of intrinsic coupling but rather a form of scattering that did not depend on the nature of the semiconducting material used.

Roberto C. Myers

The extraordinary care of the experiments and the clarity with which the mechanism of the effect was deduced has led to extraordinary attention from the condensed-matter and materials science communities. One reviewer termed this contribution “the outstanding physics paper, not only of the past year, but of the past several.”

Throughout the year, Science readers may nominate papers appearing in the journal’s research articles, reports, or reviews sections.
