Probing graphene physics | MIT News
High-quality graphite used to create graphene in Associate Professor Pablo Jarillo-Herrero’s lab comes from a mine in India, according to postdoc Javier Sanchez-Yamagishi. The graphite is rubbed on a sheet of silicon and lifted off with special tape to create thin layers of graphene.
Graphene can be tuned to behave as both an insulator …
Mott insulators, however, are a class of materials that appear from their band structure to conduct electricity, but when measured, they behave as insulators. Specifically, their energy bands are half-filled, but because of strong electrostatic interactions between electrons (such as charges of equal sign repelling each other), the material does not conduct electricity.
