    Animations | 09 Apr 2010 | Contributor(s):: Saumitra Raj Mehrotra, Gerhard Klimeck

    In solid-state physics, the electronic band structure (or simply band structure) of a solid describes ranges of energy in which an electron is "forbidden" or "allowed". The band structure is also often called the dispersion or the E(k) relationship. It is a mathematical...

11. Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride

    Presentation Materials | 06 Dec 2018 | Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan

      Graphene is a zero-bandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (h-BN) opens a bandgap in the band structure of...
