IRG A: Electronic Materials with Triangular Lattice and Dirac Excitations @ Princeton University
The research in IRG-A is focused on investigating the properties of a class of materials in which the electrons display a linear energy vs. momentum dispersion accurately described by the Dirac Hamiltonian. These "Dirac Materials" include graphene and the recently recognized topological insulators based on semi-metallic compounds of bismuth and antimony. In addition, IRG-A is interested in novel materials in which the conduction electrons are confined to 2D triangular lattices. The techniques applied involve measurement of angle-resolved photoemission, scanning tunneling microscopy, transport and magnetization.
