Goos-Hanchen like Shifts in Graphene Double Barriers    [PDF]

Ahmed Jellal, Ilham Redouani, Youness Zahidi, Hocine Bahlouli
We study the Goos-Hanchen like shifts for Dirac fermions in graphene scattered by double barrier structures. After obtaining the solution for the energy spectrum, we use the boundary conditions to explicitly determine the Goos-Hanchen like shifts and the associated transmission probability. We analyze these two quantities at resonances by studying their basic characteristics as a function of the energy and electrostatic potential parameters. Under appropriate limits, we recover previous results obtained for a single barrier.
