      abstract     = {The moiré pattern formed between a two-dimensional (2D)
                      material and the substrate has played a crucial role in
                      tuning the electronic structure of the 2D material. Here, by
                      using scanning tunneling microscopy and spectroscopy, we
                      found a moiré-pattern-dependent band gap and work function
                      modulation in hexagonal boron nitride (hBN)/Cu(111)
                      heterostructures, whose amplitudes increase with the moiré
                      pattern wavelength. Moreover, the work function modulation
                      shifts agree well with the conduction band edge shifts,
                      indicating a spatially constant electron affinity for the
                      hBN layer. Density functional theory calculations showed
                      that these observations in hBN/Cu(111) heterostructures
                      mainly originated from the hybridization of the N 3pz
                      orbital and Cu 4s orbital in different atomic
                      configurations. Our results show that the twist-angle
                      dependence of moiré patterns in hBN/Cu(111)
                      heterostructures can be used to tailor the electronic
                      properties including band gap and work function.},
