Graphene makes electrons act like they are in a magnetic field


 It began as a lab accident. When the researchers were putting graphene on the surface of a platinum crystal, the single layer of carbon atoms didn’t align perfectly, creating a strain in the structure.
Nanobubbles formed on the surface. And this caused the electrons to act like they were in a large pseudo-magnetic field.
This is a big deal because the way electrons move is fundamental to electronic devices. Manipulating how electrons move can change graphene’s conductivity and its optical or microwave properties. That’s why controlling the strain of the material is a powerful tool to have if you want to use graphene as a replacement for silicon in electronic devices.
