Electronic components built from single molecules using chemical synthesis could pave the way for smaller, faster and more green and sustainable electronic devices. Now for the first time, a transistor made from just one molecular monolayer has been made to work where it really counts. On a computer chip.
The molecular integrated circuit was created by a group of chemists and physicists from the Department of Chemistry Nano-Science Center at the University of Copenhagen and Chinese Academy of Sciences, Beijing.
Their discovery "Ultrathin Reduced Graphene Oxide Films as Transparent Top-Contacts for Light Switchable Solid-State Molecular Junctions" has just been published online in the prestigious periodical Advanced Materials. The breakthrough was made possible through an innovative use of the two dimensional carbon material graphene.
First step towards integrated molecular circuit
"Graphene has some very interesting properties, which cannot be matched by any other material.
What we have shown for the first time is that it's possible to integrate a functional component on a graphene chip.
I honestly feel this is front page news", says Norgaard.

Lottery method supplanted by precision placement
"We've made a design, that'll hold many different types of molecule" he says and goes on: "Because the graphene scaffold is closer to real chipdesign it does make it easier to test components, but of course it's also a step on the road to making a real integrated circuit using molecular components. And we must not lose sight of the fact that molecular components do have to end up in an integrated circuit, if they are going to be any use at all in real life".
The work has been supported by Danish Chinese Center for Molecular Nano-Electronics and financed by the Danish National Research Foundation, the European Union 7th framework for research (FP7) and by The Lundbeck Foundation.
