Description:
A key requirement in molecular electronics studies is the ability to measure the conductivity of a single molecule. But as Hipps explains in his Perspective, such measurements are often more about contacts than about molecular conductivity. Depending on the experimental setup, DNA behaves like a semiconductor, insulator, or metal. Cui et al. have designed a method that overcomes some of these problems, opening the door to systematic, reliable, and reproducible studies of the molecule-contact interface.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hipps, K W -- New York, N.Y. -- Science. 2001 Oct 19;294(5542):536-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and the Materials Science Program, Washington State University, Pullman, WA 99164, USA. hipps@wsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11641487" target="_blank"〉PubMed〈/a〉
