New Organic Gold - Nanoparticle Memory Device

Abstract:
Researchers have developed a new memory device that uses gold nanoparticles and the organic semiconducting compound pentacene. This novel pairing is a key step forward in the drive to develop organic "plastic" memory devices, which can be considerably cheaper and more versatile than the conventional silicon-based devices used in computers, flash drives, and other applications.

"The ability of gold nanoparticles to self-assemble into ordered arrays gives them great potential in silicon memory applications, as research has shown. We took the next step by combining them with pentacene to form a new organic memory system," said Wei Lin Leong, a materials scientist at Nanyang Technological University, in Singapore, to PhysOrg.com. Leong is the lead author of the paper describing the device, which is published in the January 23 online edition of Applied Physics Letters.
