SCANNING TRANSMISSION ELECTRON MICROSCOPY FOR QUANTITATIVE MAPPING OF MACROELEMENT CONTENTS OF CARDIAC TISSUE

Elemental mapping in scanning transmission electron microscopy

We discuss atomic resolution chemical mapping in scanning transmission electron microscopy (STEM) based on core-loss electron energy loss spectroscopy (EELS) and also on energy dispersive X-ray (EDX) imaging. Chemical mapping using EELS can yield counterintuitive results which, however, can be understood using first principles calculations. Experimental chemical maps based on EDX bear out the t...

Quantitative atomic resolution mapping using high-angle annular dark field scanning transmission electron microscopy.

A model-based method is proposed to relatively quantify the chemical composition of atomic columns using high angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) images. The method is based on a quantification of the total intensity of the scattered electrons for the individual atomic columns using statistical parameter estimation theory. In order to apply this the...

Scanning Transmission Electron Microscopy for Nanostructure Characterization

Quantitative Scanning Electron Microscopy of Surfaces

The emissive modes of secondary and backscattered electrons in a scanning electron microscope work more quantitavely for material and topographic contrasts and can better separate different types of contrast when using a multi-detector system. The detector system of conventional scanning electron microscopes often do not make the best use of the potentialities given by the electronspecimen inte...
