Abstract

We identify features in the angle-resolved photoemission spectra (ARPES) arising from the periodic pattern
characteristic for graphene heterostructure with hexagonal boron nitride (hBN). For this, we model ARPES spectra
and intensity maps for five microscopic models used previously to describe moire superlattice in graphene/ ´ hBN
systems. We show that detailed analysis of these features can be used to pin down the microscopic mechanism
of the interaction between graphene and hBN. We also analyze how the presence of a moire-periodic strain in ´
graphene or scattering of photoemitted electrons off hBN can be distinguished from the miniband formation.
