European Union sponsors fabrication of molecular electronic components on the sub-nanometer scale

Mainz chemist Angelika Kühnle participates in cross-border joint project in the field of information and communication technology

Professor Angelika Kühnle and her work group at the Institute of Physical Chemistry at Johannes Gutenberg University Mainz (JGU) are participating in a new EU project focusing on information and communication technology.

Over the next four years, a total of eight partners from six European countries will be involved in the "Planar Atomic and Molecular Scale Devices" (PAMS) project. The goal is to manufacture planar electronic components to enable technological and scientific research to be conducted at the atomic or sub-molecular level. Kühnle's work group will receive some EUR 700,000 in funding under the 7th EU Research Framework Program.

The purpose of the PAMS project is to design electronic components that will be at a scale below the sub-nanometer range, in other words, in the atomic range. In order to do so, existing tools need to be further developed so that the necessary building blocks, such as nano wires and nano pads, can be connected and manipulated at low temperatures. Among the core aims of the research project is to understand the electronic functioning of these nano wires and the contacts between the various components for further improvement.

The Mainz-based team will focus on the synthesis of tailored molecular components. "We will be producing molecular structures on surfaces that, for example, will be used as molecular wires. The essential requirement is that these structures need to be directly synthesized on a non-conducting or semi-conducting carrier layer," explained Kühnle. "For this purpose, our cooperation partners will synthesize tailored precursor molecules with clearly defined properties."

The precursor molecules will then be attached to isolating or semi-conducting surfaces under controlled conditions in an ultra-high vacuum environment. The next step will be to activate the precursor molecules on the surfaces by means of exposure to high temperatures or light irradiation. This should trigger a reaction that links the molecules, resulting in a stable, interlinked molecular component on the surface of the material.

Also participating in the EU project "Planar Atomic and Molecular Scale Devices" under supervision of Professor André Gourdon of the Centre National de la Recherche Scientifique (CNRS) in Toulouse, France, will be, in addition to Johannes Gutenberg University Mainz, the Jagiellonian University in Kraków, Poland, Dresden University of Technology, Germany, the University of Santiago de Compostela, Spain, the Spanish National Research Council in Madrid, Aalto University in Finland, and the IBM Research GmbH in Rüschlikon, Switzerland.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
