Latest Single molecule electronics Stories
Individual molecules have been used to create electrical components like resistors, transistors and diodes, that mimic the properties of familiar semiconductors. But according to Nongjian (NJ) Tao, a researcher at the Biodesign Institute® at Arizona State University, unique properties inherent in single molecules may also allow clever designers to produce novel devices whose behavior falls outside the performance observed in conventional electronics. In research appearing in today's issue...
Scientists are reporting a key advance toward the long-awaited era of "single-molecule electronics," when common electronic circuits in computers, smart phones, audio players, and other devices may shrink to the size of a grain of sand. The breakthrough is a method for creating and attaching the tiny wires that will connect molecular components, reports a new study in the Journal of the American Chemical Society.Yuji Okawa and colleagues write that the "key to single-molecule...
In research appearing in today's issue of the journal Nature Nanotechnology, Nongjian "NJ" Tao, a researcher at the Biodesign Institute at Arizona State University, has demonstrated a clever way of controlling electrical conductance of a single molecule, by exploiting the molecule's mechanical properties.Such control may eventually play a role in the design of ultra-tiny electrical gadgets, created to perform myriad useful tasks, from biological and chemical sensing to improving...
With controlled stretching of molecules, Cornell researchers have demonstrated that single-molecule devices can serve as powerful new tools for fundamental science experiments. Their work has resulted in detailed tests of long-existing theories on how electrons interact at the nanoscale.The work, led by professor of physics Dan Ralph, is published in the June 10 online edition of the journal Science. First author is J.J. Parks, a former graduate student in Ralph's lab.The scientists studied...
Researchers from Graz University of Technology, Humboldt University in Berlin, M.I.T., Montan University in Leoben and Georgia Institute of Technology report an important advance in the understanding of electrical conduction through single molecules.Minimum size, maximum efficiency: The use of molecules as elements in electronic circuits shows great potential. One of the central challenges up until now has been that most molecules only start to conduct once a large voltage has...
The smallest mechanical switch plus an electronic switch of a type never seen before. That's how physicist Marius Trouwborst sums up the results of his PhD research on electric current through atoms and molecules. "˜The ultimate aim of nanotechnology is to use molecules for electronics', he says. "˜That aim has now come a step closer.'The enormous progress in information technology is mainly related to the fact that the electronic parts in computers are getting smaller and smaller. And...
ATHENS, Ohio "” Molecular electronics is the ultimate miniaturization of electronics. In this area of research, scientists have been studying the movement of electrons through individual molecules in an effort to understand how they might control and use the process in new technologies. Computers and thousands of other devices could become vastly faster, smaller and more reliable than conventional transistor-based (wire-based) electronics.A team of Ohio University and Brazilian physicists...
