Molecules, with their precise and customizable properties, could power new computing, sensing, optical, and quantum technologies. Then, they added molecules and used nanoscale surface forces to reshape the device, letting it self-assemble without harming the molecules. To prove the method’s strength and scalability, they successfully made over 1,000 devices with molecular layers thinner than a nanometer. Finally, fluctuating nanoscale forces pulled the top electrode onto the molecules in self-aligned and non-destructive electrical contact. After that, the next electrodes are held by van der Waals forces without disrupting individual molecules, which makes it a stable structure.
