## Description

- description: 'We investigate the interplay between vertical tunneling and lateral
    transport phenomena in electrically contacted van der Waals heterostructures made
    from monolayer MoS2, hBN, and graphene. We compare data taken by low-temperature
    scanning tunneling spectroscopy to results from room-temperature conductive atomic
    force spectroscopy on monolayer MoS2 with sulfur vacancies and with varying hBN
    layers. We show that for thick hBN barrier layers, where tunneling currents into
    the conductive substrate are suppressed, a side-contact still enables addressing
    the defect states in the STM via the lateral current flow. Few-layer hBN realizes
    an intermediate regime in which the competition between vertical tunneling and
    lateral transport needs to be considered. The latter is relevant for device structures
    with both a thin tunneling barrier and a side contact to the semiconducting layers.
    Keywords: TMDC, scanning tunneling microscopy, conductive atomic force microscopy,
    defects, van der Waals heterostructure.'
