Negative differential resistances in graphene double barrier resonant tunneling diodes

(author unknown)



Yu Song, Han-Chun Wu, and Yong Guo

We theoretically investigate negative differential resistance (NDR) of massless and massive Dirac Fermions in double barrier resonant tunneling diodes based on sufficiently short and wide graphene strips. The current-voltage characteristics calculated in a rotated pseudospin space show that the ND ... [Appl. Phys. Lett. 102, 093118 (2013)] published Fri Mar 08, 2013.
