"Mesoscopic experiments tuning the relative importance of electronic interactions to observe complex ordered phases have a rich past. There is an increasing interest in the electronic properties of few-layer graphene as it offers a platform to study electronic interactions because the dispersion of bands can be tuned with number and stacking of layers in combination with electric field. I will discuss our experiments studying integer quantum Hall effect in trilayer graphene devices that are very clean; they allow us to study interactions and quantum Hall ferromagnetism.
I will start with a pedagogical introduction to the graphene family and quantum Hall physics. This talk will include experimental techniques that allow us make such clean electronic systems."
