Scanning tunneling microscopy image of a graphene nanobubble, where the hexagonal two-dimensional graphene crystal is seen distorted and stretched along three main axes, creating pseudo-magnetic fields far stronger than any magnetic field ever produced in the laboratory
Graphene, the one-atom-thick material made up of a honeycomb lattice of carbon atoms, has produced yet another in a long list of experimental surprises. Its remarkable properties have already got researchers excited regarding its applications for faster computers, cheaper and more efficient batteries and vastly higher density mass data storage. Now researchers have reported the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory – just by putting the right kind of strain onto a patch of graphene. The breakthrough could have far reaching scientific applications.
