The authors present scanning transmission electron microscopy STEM of carbon nanofibers CNFs on a bulk substrate using conventional scanning electron microscopy SEM without specimen thinning. By utilizing the electron beam tilted 85° from the substrate normal, bright-field STEM contrast is obtained for the CNFs on substrate with conventional SEM. Analysis of the observed contrast using Monte Ca...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 During the manufacturing of presentday integrated circuits, certain measurements must be made of the submicrometer structures composing the device with a high degree of repeatability. Optical microscopy, scanning electron microscopy, and the various forms of scanning probe microscopies are major microscopical techniques...

The characterization of materials supports their development and in particular of superconductors, for their technological applications. Scanning electron microscopy (SEM) is one of these characterization techniques, whose data is used to estimate the properties, determine the shortcomings and hence improve the material. The phenomenon of superconductivity initially develops within the grain an...
