This high field was crucial to the result, Shao explains, because applying a magnetic field to a material causes its electronic energy levels to become quantized into discrete (Landau) levels. The ...

It's not only magnets that push electrons to Landau levels. Two-dimensional graphene, consisting of a single layer of atoms, can do it too. Normally, graphene is conductive; but if you warp or ...

and fully valley- and spin-polarized Landau levels, hence the flavors that affect the FQH phases, in MoS 2 are unique compared to other materials systems (actually, there are so far only graphene ...
