Metallic transition metal dichalcogenides like tantalum diselenide (TaSe2) exhibit exciting behaviors at low temperatures including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to classify the

Geometric interference in a high-mobility graphene annulus p-n junction device

Son Le, Albert Rigosi, Joseph Hagmann, Christopher Gutierrez, Ji Ung Lee, Curt A. Richter
The emergence of interference is observed in the resistance of a graphene annulus pn junction device as a result of applying two separate gate voltages. The observed resistance patterns are carefully inspected, and it is determined that the position of the
