Quantitative High Resolution Transmission Electron Microscopy - The Role of Space Charge in Blurring Images

  • A. M. Schwartz (a1), J. M. Gibson (a1) and T. Zheng (a2)

Abstract

We investigate space-charge by analytic methods and Monte Carlo simulations as a possible source of blur in high-resolution TEM images. In doing so we believe to have identified a novel type of space charge effect, namely quantum space charge(QSC) effect. We predict the blur for typical HRTEM images and for electron holograms. Inclusion of this hitherto unrecognized effect in image simulations (and experimental design for HRTEM and related techniques, such as holography) should permit further progress in the critical field of quantitative HRTEM image matching as a means for atomic structure determination.
