Contrast of Backscattered Electron SEM Images of Nanoparticles on Substrates with Complex Structure
This study is concerned with backscattered electron scanning electron microscopy (BSE SEM) contrast of complex nanoscaled samples which consist of SiO2 nanoparticles (NPs) deposited on indium-tin-oxide covered bulk SiO2 and glassy carbon substrates. BSE SEM contrast of NPs is studied as function of the primary electron energy and working distance. Contrast inversions are observed which prevent ...
متن کاملAtomic number and crystallographic contrast images with the SEM: a review of backscattered electron techniques
Backscattered electrons (BSE) are incident electrons reflected back from a target specimen and imaged with the scanning electron microscope (SEM). Three distinct BSE signals exist: atomic number or Z-contrast, in which composition determines image contrast; orientation contrast, in which specimen crystal structure determines image contrast; and electron channelling patterns (ECP), which are uni...
متن کاملNano-Structure Roughening on Poly(Lactic Acid)PLA Substrates: Scanning Electron Microscopy (SEM) Surface Morphology Characterization
Scanningelectron microscopy (SEM) has been utilized to examine the morphology and topography alterations in the surface of Poly(Lactic Acid)(PLA) fabrics due to UV/Ozoneirradiation. In the past decade, a growing attention in the usage of “Green Techniques” in industrial applications has been observed owing to many benefits such as low impurities and their relatively low cost to substitute th...

15 صفحه اولAnomalous Atomic Number Contrast in Compositional Backscattered Electron Images of Organic Compounds Due to Cathodoluminescence
It is generally accepted that when multi-component materials are examined with a scanning electron microscope, the contrast differences observed using compositional backscattered electron imaging are due to variations in their average atomic numbers. With increasing atomic number, there is an approximate monotonic increase in backscatter coefficient, which is observed as an increase in the brig...
