Electron localization in periodically strained graphene

Pseudo-magnetic field (PMF) in deformed graphene has been proposed as a promising and flexible method to quantum-confine electronic states create gaps the local density of states. Motivated by this perspective, we numerically analyze various different configurations leading localization band flattening periodically strained graphene. In particular, highlight existence fine structure pseudo-Landau levels confined large-PMF regions, emergence PMF nodes well snake-like orbits. our paper, further importance relative rotation asymmetry strain lattice with respect atomic show how it can be used modulate periodicity localized orbits far from points. Possible implementations applications simulated structures are discussed.
