Determination of three-dimensional structure in photon scanning tunnelling microscopy
We present an analytic solution to the problem of determining three-dimensional object structure, described by the spatial dependence of the susceptibility, from data accessible through photon scanning tunnelling microscopy (PSTM) experiments. An analysis is presented of the scattering of evanescent waves with detection of the scattered field by a probe in the near zone of the scatterer. The re...
متن کاملExciton dynamics of C60-based single-photon emitters explored by Hanbury Brown–Twiss scanning tunnelling microscopy
Exciton creation and annihilation by charges are crucial processes for technologies relying on charge-exciton-photon conversion. Improvement of organic light sources or dye-sensitized solar cells requires methods to address exciton dynamics at the molecular scale. Near-field techniques have been instrumental for this purpose; however, characterizing exciton recombination with molecular resoluti...
متن کاملPhoton-assisted tunnelling with nonclassical light
Among the most exciting recent advances in the field of superconducting quantum circuits is the ability to coherently couple microwave photons in low-loss cavities to quantum electronic conductors. These hybrid quantum systems hold great promise for quantum information-processing applications; even more strikingly, they enable exploration of new physical regimes. Here we study theoretically the...
متن کاملScanning tunnelling microscopy of suspended graphene.
Suspended graphene has been studied by STM for the first time. Atomic resolution on mono- and bi-layer graphene samples has been obtained after ridding the graphene surface of contamination via high-temperature annealing. Static local corrugations (ripples) have been observed on both types of structures.
متن کاملScanning tunnelling microscopy studies of silicides
We review the topic of scanning tunnelling microscopy (STM) studies of silicides, with an emphasis on fundamental scientific issues that can be addressed using STM and ballistic-electron-emission microscopy (BEEM). The discussion is organized according to the topics of structure (atomic scale precursors, surface reconstructions, bulk structures, interfaces) kinetics and growth (direct atomic me...
