      "summary": "Transport measurements in aligned graphene–hexagonal-boron-nitride superlattices revealed oscillations periodic in inverse magnetic field that remained visible at 373 K in fields of a few tesla. Their principal maxima followed one flux quantum per integer number of superlattice cells, with a period largely independent of carrier density. Comparison with misaligned devices, capacitance measurements and magnetic-miniband modelling supported an interpretation through recurring Bloch states rather than thermally resolved Landau gaps.",

Comparison with misaligned devices, capacitance measurements and magnetic-miniband modelling supported an interpretation through recurring Bloch states rather than thermally resolved Landau gaps. The measured result concerns the investigated graphene superlattices and accessible carrier densities, temperatures and fields.
