Hexagonal boron nitride is a large band gap layered crystal, frequently incorporated in van der Waals heterostructures as an insulating or tunnel barrier. Localised states with energies within its band gap can emit visible light, relevant to applicat... Read More about Tunnel spectroscopy of localised electronic states in hexagonal boron nitride.

High-order fractal states in graphene superlattices (2018)
Journal Article
Krishna Kumar, R., Mishchenko, A., Chen, X., Pezzini, S., Auton, G., Ponomarenko, L., …Geim, A. (2018). High-order fractal states in graphene superlattices. Proceedings of the National Academy of Sciences, 115(20), https://doi.org/10.1073/pnas.1804572115

Graphene superlattices were shown to exhibit high-temperature quantum oscillations due to periodic emergence of delocalized Bloch states in high magnetic fields such that unit fractions of the flux quantum pierce a superlattice unit cell. Under these... Read More about High-order fractal states in graphene superlattices.
