abstract = {Encapsulating few-layer graphene (FLG) in hexagonal boron
nitride (hBN) cancause nanoscale inhomogeneities in the FLG,
including changes in stackingdomains and topographic
defects. Due to the diffraction limit, characterizingthese
inhomogeneities is challenging. Recently, the visualization
of stackingdomains in encapsulated four-layer graphene (4LG)
has been demonstratedwith phonon polariton (PhP)-assisted
near-field imaging. However, theunderlying coupling
mechanism and ability to image
subdiffractional-sizedinhomogeneities remain unknown. Here,
direct replicas and magnifiedimages of
subdiffractional-sized inhomogeneities in hBN-covered
trilayergraphene (TLG) and encapsulated 4LG, enabled by the
hyperlensing effect,are retrieved. This hyperlensing
effect is mediated by hBN’s hyperbolic PhPthat couple to
the FLG’s plasmon polaritons. Using near-field
microscopy, thecoupling is identified by determining the
polariton dispersion in hBN-coveredTLG to be
stacking-dependent. This work demonstrates super-resolution
andmagnified imaging of inhomogeneities, paving the way for
the realization ofhomogeneous encapsulated FLG transport
samples to study correlatedphysics},
