Scientists are constantly trying to discover new materials to enable the development of new technologies. One such material is 2D metals, which have unusual properties that come from quantum confinement. This trait has already been harnessed in materials like graphene and quantum dots for various applications. However, creating 2D metals has faced one hurdle: metal atoms repel each other, making them unlikely to assemble in a structured manner desirable for 2D materials. That is until now, a team of scientists in Germany has managed to create two versions of 2D metals proving that theoretical concept can actually work.

The study, published in Nature, details the successful experimentation with single layers of chromium atoms and monolayers of copper. The researchers were able to overcome the sticky issue of metal atoms self-repelling by using a very small number of layers, enabling the atoms to behave like they are in a 3D environment, with the 2D context allowing the atoms to bond with each other. This new discovery opens the door for more research into the world of 2D metals, which will be critical for future technologies.

This is a breakthrough for the scientific community, representing the intersection of two fields of physics with the potential for real-world technological applications. We can expect future developments to come from this niche of quantum materials.
