Short description: Seminar - Dean Moldovan

Graphene has a very interesting reaction to geometric deformations of its lattice. Electrons in the strained region behave as if they are exposed to a magnetic field, even though there is no real external field. This has led to the naming of this strain-induced effect as 'pseudo-magnetic'. Graphene's excellent mechanical properties allow it to sustain elastic strain up to 25% which result in extremely high pseudo-magnetic fields measured in hundreds of Tesla.
