<p>We investigate the electronic properties of a graphene nanobubble superlattice realized as a periodic array of Gaussian-shaped deformations. The periodic strain induces modification of band structures leading to the emergence of new features. In particular, the density of states (DOS) exhibits a series of sharp peaks as a function of the bubble size, while the overall DOS profile remains nearly constant. These peaks are interpreted as signatures of pseudo-Landau levels (pLLs) formed under the influence of the strain-induced pseudomagnetic field (PMF). Furthermore, resonant peaks in conductance are observed near the DOS maxima, and the corresponding current densities are found to be spatially localized around the nanobubbles. These results collectively support the interpretation that the DOS peaks originate from discrete pLLs generated by the periodic pseudomagnetic field in the strained graphene lattice.</p>
