Abstract
We study tunneling of Dirac particles through Kronig-Penney models on general lattices, computing their transmission coctTicient. We subsequently focus our attention on the Fibonacci lattice as a typical example of a quasi crystaL Wc compare our results to the non-relativistic ones, and find a shrinkage ofthe spectrum similar to that of per iodic systems.
