Experimental techniques such as nano-ARPES are expected to provide an opportunity to measure the electronic properties of disordered nanomaterials directly. However, the interpretation of the spectra is not quite simple as it contains complicated quantum mechanical effects related to the measurement process itself. In this talk, I would like to demonstrate a novel approach that can overcome this conundrum by corroborating the experimental results with an adequate simulation. Ab. initio calculation on arbitrarily shaped or chemically ornamented nanostructures is elaborately correlated to the photoemission theory, a method also known as independent atomic center approximation (IAC). This correlation can be directly exploited to interpret the experimental results. To test this study, a direct comparison was made between the calculation results and experimental results on pentacene molecule and highly oriented pyrolytic graphite (HOPG). As a general extension, the unique electronic structures of nano-sized graphene oxide and features from the experimental result of black phosphorous (BP) are disclosed for the first time as supportive evidence for the usefulness of this method. This work opens an unprecedented approach to intuitive and practical understanding of the electronic properties of disordered nanomaterials.
