Goodbye, Silicon? On the way to new materials for electronics
In certain cases, a new organometallic material could replace silicon as a semiconductor, as show the experiments conducted by a group of scientists from Bulgaria, Germany and Spain. The material can be produced by simple means at room temperature. Scientists see potential applications above all in optoelectronics.

The MPI-P scientists used ultrafast terahertz spectroscopy to characterize the unique properties of the produced network. These measurements showed that the mobility of electrons in this material is higher by a factor of 10,000 than that in insulator MOFs. This means that when an electric field is applied in the MOF, electrons can move over long distances, an effect that could be measured in 1000 µm long samples. Therefore, the new material paves the way for the use of metal-organic networks in optoelectronics.

Next, the researchers want to work on modifying and predicting the electronic properties of the material directly during production via the composition of the MOF. They have now published their research results in the renowned journal "Nature Materials".
