Retrieving Potential Maps from Reversed Multislice Calculations

Abstract: Quantitative applications of high resolution TEM are often bottlenecked by the complexity of the formed lattice images. In general terms, lattice images do not reveal the real atomic structure of the sample directly, can be distorted, and information about the sample thickness and chemical composition are heavily encoded. These drawbacks relate to the presence of lens aberrations and dynamic diffraction. The development of Cs corrected TEM [1, 2] and software that reconstructs the complex electron exit wave fu… Show more

“…Models and techniques have been proposed to attempt to invert from the exit surface wave function to the specimen potential [5][6][7], but their application is not yet routine. If much is already known about the specimen, then there are more options for interpreting the images [8,9]. But for specimens which are unknown in detail, obtaining element specific information from HRTEM alone is challenging.…”
