In a recent study conducted by the Department of Micro and Nanosystems at KTH has tested a technique that will help in forming millions of feasible nanoscale molecular junctions. The study also published in Nature Communications. The scope of growth for electronics depends on how the abilities of silicon conductors can be exploited. The recent work at KTH may help in providing large creation of the nanoscale electrodes that are required to explore molecules and exploit their behavior as possibly valuable electronic materials.

The researchers at KTH testified that with thin materials of 100 mm diameter wafer they could produce approximately 20 million electrodes with five hours. In this, they will be using gold film on top of a fragile material that forms cracks. Furthermore, while operating with the van der Zant Lab at TU Delft, the group studied a largely employed reference molecule in the nanometer-wide space between the electrodes to make sure that the fabrication method didn't hamper the construction of molecular junctions.

The co-author of the experiment, Shyamprasad Natarajan Raja said that the method of "crack-defined break junction" proposes an advancement to a scalable production of the structure from a position of standstill. This will further open ways from which electronic devices can be made of single molecules. He also added by saying break junctions are the most appropriate means currently at disposal to make single molecules share of a larger electronic circuit that can examine molecules.
