## Description

- description: Scientific instruments for material characterization have recently
    been improved to yield big data. For instance, scanning transmission electron
    microscopy (STEM) allows us to acquire many diffraction patterns from a scanning
    area, which is referred to as four-dimensional (4D) STEM. Here we study a combination
    of 4D-STEM and a statistical technique called non-negative matrix factorization
    (NMF) to deduce sparse diffraction patterns from a 4D-STEM data consisting of
    10,000 diffraction patterns. Titanium oxide nanosheets are analyzed using this
    combined technique, and we discriminate the two diffraction patterns from pristine
    TiO2 and reduced Ti2O3 areas, where the latter is due to topotactic reduction
    induced by electron irradiation. The combination of NMF and 4D-STEM is expected
    to become a standard characterization technique for a wide range materials.
