In best circles: First integrated circuit from self-assembled polymer

19.02.2018

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used for logic operation in digital circuits and are the building blocks of an integrated circuit. The radical concept of self-assembled electronics has been around since 1976. For decades, the challenge has been to form a self-assembled monolayer of a semiconducting polymer in a transistor.

“The idea is that all components of a transistor come together and arrange themselves in a hierarchical order”, said Kamal Asadi, leader of the Humboldt research group at the MPI for Polymer Research. The monolayer is highly ordered and is able to conduct electric charge carriers well. The research team has used solution of a polymer. By dipping the transistor substrate in the solution in a controlled manner, the researchers could grow and produce a complete polymeric monolayer.

Scientific breakthrough

To achieve their scientific breakthrough, the scientists have intentionally dissolved the semiconducting polymer in an organic solvent that could not fully dissolve the polymer. In this way, the scientists have made the first self-assembled monolayer polymer field-effect transistor (PoM-FET). Nevertheless, one PoM-FET does not make a functional integrated circuit.

Therefore, the research team has integrated hundreds of PoM-FETs and has operated them at the same time to demonstrate a 15-bit code generator, an integrated circuit that converts a voltage into a digital code. The landmark scientific result has applications in flexible electronics and fast response sensors.

International research collaboration

The scientific work was a collaboration of several international research groups worldwide. The semiconducting polymer was synthesized by the group of Professor He Yan at the Hong Kong University of Science and Technology, Hong Kong. The polymeric monolayers were analyzed by the group of Professor Harald Ade at the North Carolina State University in USA, and by the group of Professor Wojtek Pisula at the Lodz University of Technology, Poland. The PoM-FETs and the integrated circuits were fabricated at the MPI for Polymer Research, Mainz, Germany. Post-doctoral researcher Mengmeng Li conducted the research work that was led by Kamal Asadi together with Wojtek Pisula.

About the Max Planck Institute for Polymer Research

The Max Planck Institute for Polymer Research (MPI-P) ranks among the globally leading research centers in the field of polymer research since its foundation in 1984. The focus on soft materials and macromolecular materials has resulted in the worldwide unique position of the MPI-P and its research focus. Fundamental polymers research on both production and characterization as well as analysis of physical and chemical properties are conducted by scientific collaborators from all over the world. Presently over 500 people are working at the MPI-P, the vast majority of whom are engaged in scientific research.

Im Focus: Better thermal conductivity by adjusting the arrangement of atoms

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.

In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Im Focus: Megakaryocytes act as „bouncers“ restraining cell migration in the bone marrow

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.

Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...

Im Focus: Artificial neural network resolves puzzles from condensed matter physics: Which is the perfect quantum theory?

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.

Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...

Im Focus: Extremely hard yet metallically conductive: Bayreuth researchers develop novel material with high-tech prospects

An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".

The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
